The critical values for a 2-tailed sign test for 13-coin flips (alpha of. 05) is: ± 1.96

For given question,

We need to find the critical values for a 2-tailed sign test for 13-coin flips.

We have been given an alpha level of 0.05 that is 5%

⇒ α = 0.05

We know that in hypothesis testing, a critical value is a point on the test distribution that is compared to the test statistic to determine whether to reject the null hypothesis.

These are the points on the distribution which have the same probability as your test statistic, equal to the significance level α.

The critical values are assumed to be at least as extreme at those critical values.

Now we find 1 - α

⇒ 1 - α = 1 - 0.05

⇒ 1 - α = 0.95

Because it is a two-tailed test, we are going to divide 0.95 by 2.

⇒ 0.95/2 = 0.475

Now we look in the z-table to find out cutoff points.

For the area of 0.475, the critical values is ± 1.96 .

Therefore, the critical values for a 2-tailed sign test for 13-coin flips (alpha of. 05) is: ± 1.96

The results generated in the map phase are combined in the _reduce_ phase.

In maps, the "reduced phase" refers to a technique used to remove the phase ambiguity present in interferometric synthetic aperture radar (InSAR) data. InSAR uses radar to measure the distance between a satellite or aircraft and the ground and can be used to create detailed maps of changes in the surface of the earth over time.

However, because InSAR data is collected using radar waves, which are sensitive to the phase of the signal, the data can be affected by phase ambiguities. The reduced phase technique is used to remove these ambiguities and create more accurate maps.

Therefore, The results generated in the map phase are combined in the _reduce_ phase.

The given statement "regard to resistance training for youth, progression should be based on postural control and not the amount of weight that can be used." is true.

In order to create sufficient motor output to maintain a controlled, upright posture, our central nervous system (CNS) manages sensory input from those other systems in a process called as postural control. The primary sensory receptors involved in postural control and balance are the somatosensory, vestibular, and visual systems.

Postural control's 2 main objectives are postural orientation and balance.

For the purposes of carrying a particular activity, postural orientation entails the ability to maintain an acceptable relationship between the body's parts (ortho) and between the and the environment (using various sensory inputs).

Postural stability is accomplished when sensorimotor mechanisms are coordinated to maintain the body's center of mass across both identity and externally induced stimuli.

Answer:

7. To perform a t-test when the sample size is small, the sample must show no evidence of strong skewness and must contain no outliers.

Step-by-step explanation:

These are the two conditions required for performing a t test

- Sample Size: A small sample size can reduce the statistical power of a t-test, making it more challenging to detect significant differences between groups. Generally, a larger sample size is desirable to obtain more reliable and representative results.

- Skewness: Skewness refers to the asymmetry of the distribution of data. In a t-test, assuming normality of the data is important for accurate results. If the data exhibits strong skewness, the assumption of normality may be violated. In such cases, alternative non-parametric tests or transformations of the data may be more appropriate.

- Outliers: Outliers are extreme values that significantly differ from the rest of the data. They can have a disproportionate impact on the results of a t-test, particularly when the sample size is small. Outliers can distort the mean and affect the assumptions of normality and homogeneity of variance.

While the presence of skewness or outliers does not prohibit the use of a t-test with a small sample size, it is important to interpret the results with caution and consider alternative approaches if necessary. Robust statistical methods, such as non-parametric tests or bootstrapping, can be useful when dealing with non-normal or outlier-prone data, especially with small sample sizes. Additionally, visual inspection of the data distribution, such as through histograms or box plots, can help identify potential skewness or outliers.

Based on the information provided, it appears that the regression model has found a statistically significant relationship between the outcome variable and the response variables while controlling for the effects of the two co-variables.

However, the R2 value of only 11.5% suggests that the model is explaining only a small portion of the variability in the outcome variable. This may indicate that there are other important factors that are not being accounted for in the model. It is also possible that the co-variables included in the model are not strong predictors of the outcome variable. Further investigation and analysis may be needed to fully understand the relationship between the variables and to improve the predictive power of the model.

The quotient is (78 + 11i) / 85. To find the quotient in the standard 2-9i form, we need to divide the numerator by the denominator.

Let's divide 3-8i by 2-9i. To simplify this division, we can use the complex conjugate of the denominator. The complex conjugate of 2-9i is 2+9i.

Now, we multiply both the numerator and the denominator by the complex conjugate of the denominator:

(3-8i) * (2+9i) / (2-9i) * (2+9i)

Expanding the numerator and the denominator:

(6 + 27i - 16i - 72i^2) / (4 + 18i - 18i - 81i^2)

Simplifying the terms:

(6 + 11i - 72i^2) / (4 - 81i^2)

Since i^2 is equal to -1, we can substitute:

(6 + 11i - 72(-1)) / (4 - 81(-1))

Simplifying further:

(6 + 11i + 72) / (4 + 81)

(78 + 11i) / 85

78/85 + (11/85)i

Therefore, the quotient in the standard form is  (78 + 11i) / 85.

The average rate of change of f(x) over the interval [-1, 1] is -1.

To find the average rate of change of f(x) over the interval [-1, 1], we need to use the formula:

Average rate of change = [f(1) - f(-1)] / [1 - (-1)]

First, let's find f(1) and f(-1):

f (x) = x² - x - 1

f(1) = 1 - 1 - 1 = -1

f(-1) = (-1)² - (-1) - 1 = 1

Now we can plug these values into the formula:

Average rate of change = (-1 - 1) / (1 - (-1))

                                     = -2/2

                                    = -1

Hope that this is helpful.

To estimate the number of new users that would be added during time period 7, we can use the Bass diffusion model, which is commonly used to model the adoption of new products or technologies.

The Bass diffusion model is given by the formula:

\(\[N(t) = \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot t)}}}\]\)

where:

- N(t) represents the cumulative number of adopters at time \(t\).

- p is the innovation parameter, representing the coefficient of innovation.

- q is the imitation parameter, representing the coefficient of imitation.

- e is the base of the natural logarithm.

Given a population size of 67 million, an innovation parameter of 0.005, and an imitation parameter of 0.84 for Color TV, we can substitute these values into the Bass diffusion model and calculate the number of new users added during time period 7.

\(\[N(7) - N(6) = \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot 7)}}} - \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot 6)}}}\]\)

Substituting the given values into the equation:

\(\[N(7) - N(6) = \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 7)}}} - \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 6)}}}\]\)

Evaluating the expression will give us the estimated number of new users added during time period 7.

In LaTeX, the solution can be represented as:

\(\[N(7) - N(6) = \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 7)}}} - \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 6)}}}\]\)

After evaluating this expression, you will obtain the estimated number of new users added during time period 7.

The diagram below would be helpful

From the diagram above, a segment has been made from C to O indicating the radius of the circle, so CO is a radius.

Also any line drawn from the center of a circle to touch the circumference is a radius, So, OB is a radius too.

Since CO and OB are radii of the circle, then their sides are equal,

Hence triangle COB is an isosceles triangle.

Also the line OA represents the radius of the circle just like CO. Since OA and CO are radii,

Hence triangle COA is an isosceles triangle.

(b) Statement: AOB is a straight line and at the center of a circle

Reason: Given

Statement: AOB is also an angle, which is 180 degrees

Reason: Angle on a straight line is 180 degrees

Statement: Angle AOB is an angle at the center of the circle, and angle C is at the circumference

Reason: same arc AB

Statement: Angle AOB = 2C

Reason: Angle at the center of a circle is twice angle at the circumference.

Hence
