Please only answer C & D 

Is a weight loss program based on exercise less effective than a program based on diet? The 46 overweight
people put on a strict one year exercise program lost an average of 21 pounds with a standard deviation of
10 pounds. The 55 overweight people put on a strict one year diet lost an average of 22 pounds with a
standard deviation of 7 pounds. What can be concluded at the a = 0.10 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Hp: Select an answer V
Select an answer V
Select an answer V
(please enter a decimal)
H: Select an answer V

c. The test statistic
(please show your answer to 3 decimal places.)
=
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is ?va
f. Based on this, we should Select an answer
| the null hypothesis.
g. Thus, the final conclusion is that ..
O The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude
that the population mean weight loss on the exercise program is less than the population mean
weight loss on the diet.
O The results are statistically insignificant at a = 0.10, so there is insufficient evidence to
conclude that the population mean weight loss on the exercise program is less than the
population mean weight loss on the diet.
O The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude
that the mean weight loss for the 46 participants on the exercise program is less than the mean
weight loss for the 55 participants on the diet.
O The results are statistically insignificant at a = 0.10, so there is statistically significant
evidence to conclude that the population mean weight loss on the exercise program is equal to
the population mean weight loss on the diet.
h. Interpret the p-value in the context of the study.
