Question

Is there a significant difference in weight loss between the two levels of exercise program, regardless of gender? Explain your decision. Rationalize your decision by using the appropriate p value and explaining how it was used to make your decision

Answer 1

o determine whether there is a significant difference in weight loss between two levels of exercise program, regardless of gender, we would need to conduct a statistical hypothesis test. We would use a two-sample t-test to compare the mean weight loss between the two levels of exercise program.

The null hypothesis would be that there is no significant difference in weight loss between the two levels of exercise program, while the alternative hypothesis would be that there is a significant difference in weight loss between the two levels of exercise program.

We would then calculate the p-value, which represents the probability of observing a test statistic as extreme as the one calculated from the sample data, assuming the null hypothesis is true. If the p-value is less than the significance level (usually set at 0.05), we would reject the null hypothesis and conclude that there is a significant difference in weight loss between the two levels of exercise program.

Without knowing the data, it is not possible to determine the appropriate p-value or make a decision about the significance of the difference in weight loss between the two levels of exercise program.
