Question

The following data was calculated during a the study on physical therapy patients. Now find the critical value(s) and sketch

the rejection region in order to interpret the results for this hypothesis test:

..

• A physical therapist would like to test the claim that the average amount of time a physical therapy patient exercises at

home weekly is less than 50 minutes.

.

• Significance level = 0.01

.

• Sample size 29 physical therapy patients

• Test statistic to = -1.72

Use the curve below to help visualize your answer. Select the correct sample size by dragging the black point along the slider

and the appropriate test by dragging the blue point to a right-, left- or two-tailed diagram. Then, set the critical value(s) on

the z-axis to select the appropriate answer.

O

Move the blue dot to choose the appropriate test

n=26

rejection region = 0.123

t=-1.19

test statistic = 0

Select the correct answer below:

O

Reject Ho. There is strong evidence to conclude that theaverage amount of time a physical therapy

patient exercises at home weekly is less than 50 minutes.

O

Reject Ho. There is NOT strong evidence to conclude that the average amount of time a physical therapy

patient exercises at home weekly is less than 50 minutes.

Fail to reject Ho. There is strong evidence to conclude that the average amount of time a

physical therapy

patient exercises at home weekly is less than 50 minutes.

Fail to reject He: There is NOT strong evidence to conclude that the average amount of time a physical therapy

patient exercises at home weekly is less than 50 minutes.

Question The following data was calculated during a the study on physical therapy patients. Now find the critical value(s) and sicetch the rejection region in order to interpret the results for this hypothesis test: - A physical therapist would like to test the claim that the average amount of time a physical therapy patient exercises at home weekly is less than 50 minutes. - Significance level $=0.01$ - Sample size $=29$ physical therapy patients - Test statistic $t_{0}=−1.72$ Use the curve below to help visualize your answer. Select the correct sample size by dragging the black point aliong the slider and the appropriate test by dragging the blue point to a right-, left- or two-talled diagram. Then, set the critical value(s) on the $x$-axis to select the appropriate answer. $n=26$ Move the blue dot to choose the appropriate test
