Is a weight loss program based on exercise less effective than a program based on diet? The 45 overweight
people put on a strict one year exercise program lost an average of 25 pounds with a standard deviation of
9 pounds. The 45 overweight people put on a strict one year diet lost an average of 30 pounds with a
standard deviation of 6 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:
Ho: Select an answer
H₁: Select an answer

(please enter a decimal)
Select an answer (Please enter a decimal)
c. The test statistic?v=
d. The p-value=
e. The p-value is ? a
f. Based on this, we should Select an answer the null hypothesis.
g. Thus, the final conclusion is that ...
(please show your answer to 3 decimal places.)
(Please show your answer to 4 decimal places.)
O The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude
that the mean weight loss for the 45 participants on the exercise program is less than the
mean weight loss for the 45 participants on the diet.
O The results are statistically insignificant at = 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.
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 x = 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.
h. Interpret the p-value in the context of the study.
O If the sample mean weight loss for the 45 participants on the exercise program is the same as
the sample mean weight loss for the 45 participants on the diet and if another 45 participants
on the exercise program and 45 participants on the diet are weighed then there would be a
0.13% chance of concluding that the mean weight loss for the 45 participants on the exercise
program is at least 5 pounds less than the mean weight loss for the 45 participants on the diet
O There is a 0.13% chance of a Type I error.
O If the population mean weight loss on the exercise program is equal to the population mean
weight loss on the diet and if another 45 and 45 participants on the exercise program and on
the diet are observed then there would be a 0.13% chance that the mean weight loss for the 45
participants on the exercise program would be at least 5 pounds less than the mean weight loss
for the 45 participants on the diet.
O There is a 0.13% chance that the mean weight loss for the 45 participants on the exercise
program is at least 5 pounds less than the mean weight loss for the 45 participants on the diet.
i. Interpret the level of significance in the context of the study.
O There is a 10% chance that there is a difference in the population mean weight loss between
those on the exercise program and those on the diet.
O There is a 10% chance that you are such a beautiful person that you never have to worry about
your weight.
O If the population mean weight loss on the exercise program is equal to the population mean
weight loss on the diet and if another 45 and 45 participants on the exercise program and on
the diet are observed then there would be a 10% chance that we would end up falsely
concluding that the population mean weight loss on the exercise program is less than the
population mean weight loss on the diet
O If the population mean weight loss on the exercise program is equal to the population mean
weight loss on the diet and if another 45 and 45 participants on the exercise program and on
the diet are observed then there would be a 10% chance that we would end up falsely
concluding that the sample mean weight loss for these 45 and 45 participants differ from each
other.
