Question

a. state the null and alternative hypothesis

b. find the rejection region and decision at a= .05

In a dieting program 8 participants were randomly selected and interviewed. Their weights as they
entered the program and their weights (in pounds) after 10 weeks are as follows:
Before 214 211 195 153 165 168 175 180
After 211 208 190 154 165 169 170 179
The difference in the weights (before-after) for this sample results in d-1.875 and sa-2.475.
Assume that the weights are approximately normally distributed.
