I Weight loss program based on exercise more effecttve than a program based on diet? The 44 overwelght people put on a strict one year exercise program lost an average of 30 pounds with a standard devlation of 10 pounds. The 50 overweight people put on a strict one year diet lost an average of 25 pounds with a standard deviation of 9 pounds. What can be concluded at the a = 0.01 level of signtficance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answerv Select an answerv Select an answerv (please enter a decimal) H: Select an answerv Select an answervSelect an answerv (Please enter a decimal) C. The test statistic ?v = (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 ?v a f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that ... O The results are statistically insigntficant at a = 0.01, so there is insufficient evidence to conclude that the population mean weight loss on the exercise program is more than the population mean weight loss on the diet. O The results are statistically insignificant at a = 0.01, so there is stațistically 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 significant at a = 0.01, so there is sufficient evidence to conclude that the mean weight loss for the 44 participants on the exercise program is more than the mean weight loss for the 50 participants on the diet. O The results are statiştically significant at a 0.01, so there is sufficient evidence to conclude that the population mean weight loss on the exercise program is more 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 44 participants on the exercise program is the same as the sample mean weight loss for the 50 participants on the diet and if another 44 participants on the exercise program and 50 participants on the diet are weighed then there would be a 0.65% chance of concluding that the mean weight loss for the 44 participants on the exercise program is at least 5 pounds more tban the mean weiaht loSs for the 50inarticinants on the diet

that the population mean weight loss on the exercise program is more 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 44 participants on the exercise program is the same as
the sample mean weight loss for the 50 participants on the diet and if another 44 participants
on the exercise program and 50 participants on the diet are weighed then there would be a
0.65% chance of concluding that the mean weight loss for the 44 participants on the exercise
program is at least 5 pounds more than the mean weight loss for the 50 participants on the diet
O There is a 0.65% chance that the mean weight loss for the 44 participants on the exercise
program is at least 5 pounds more than the mean weight loss for the 50 participants on the
diet.
O There is a 0.65% 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 44 and 50 participants on the exercise program and on
the diet are observed then there would be a 0.65% chance that the mean weight loss for the 44
participants on the exercise program would be at least 5 pounds more than the mean weight
loss for the 50 participants on the diet.
1. Interpret the level of significance in the context of the study.
O There is a 1% chance that there is a difference in the population mean weight loss between
those on the exercise program and those on the diet.
OIf the population mean weight loss on the exercise program is equal to the population mean
weight loss on the diet and if another 44 and 50 participants on the exercise program and on
the diet are observed then there would be a 1% chance that we would end up falsely
concluding that the population mean weight loss on the exercise program is more than the
population mean weight loss on the diet
O There is a 1% 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 44 and 50 participants on the exercise program and on
the diet are observed then there would be a 1% chance that we would end up falsely
concluding that the sample mean weight loss for these 44 and 50 participants differ from each
other.

Is a Welght loss program based on exercise more effective than a program based on diet? The 44 overwelght
people put on a strict one year exercise program lost an average of 30 pounds with a standard devlation of
10 pounds. The 50 overweight people put on a strict one year diet lost an average of 25 pounds with a
standard deviation of 9 pounds. What can be concluded at the a = 0.01 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho: Select an answerv Select an answerv Select an answerv (please enter a decimal)
H: Select an answerv Select an answerv Select an answerv (Please enter a decimal)
C. The test statistic ?v =
(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 ?v a
f. Based on this, we should Select an answerv the null hypothesis.
g. Thus, the final conclusion is that ...
O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to
conclude that the population mean weight loss on the exercise program is more than the
population mean weight loss on the diet.
O The results are statistically insignificant at a = 0.01, so there is stațistically 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 significant at a = 0.01, so there is sufficient evidence to conclude
that the mean weight loss for the 44 participants on the exercise program is more than the
mean weight loss for the 50 participants on the diet.
O The results are statiștically significant at a = 0.01, so there is sufficient evidence to conclude
that the population mean weight loss on the exercise program is more 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 44 participants on the exercise program is the same as
the sample mean weight loss for the 50 participants on the diet and if another 44 participants
on the exercise program and 50 participants on the diet are weighed then there would be a
0.65% chance of concluding that the mean weight loss for the 44 participants on the exercise
program is at least 5 pounds more than the mean weight loSs for the 50narticinants on the diet
