1. Resveratrol, an ingredient in red wine and grapes, has beenshown to promote weight loss in rodents. One study investigateswhether the same phenomenon holds true in primates. The grey mouselemur, a primate, demonstrates seasonal spontaneous obesity inpreparation for winter, doubling its body mass. A sample of sixlemurs had their resting metabolic rate, body mass gain, foodintake, and locomotor activity measured for one week prior toresveratrol supplementation (to serve as a baseline) and then thefour indicators were measured again after treatment with aresveratrol supplement for four weeks. Some p-values for testscomparing the mean differences in these variables are given below.In parts a-d, state the conclusion of the test using a 5%significance level, and interpret the conclusion in context. (HINT:For thinking of the null/alternative hypothesis, the null would bethat there is no change and the alternative would be what they aretrying to test as described in the wording in each part)
a. In a test to see if mean resting metabolic rate is higherafter treatment, p=0.013
b. In a test to see if mean body mass gain is lower aftertreatment, p=0.007
c. In a test to see if mean food intake is affected by thetreatment, p=0.035
d. In a test to see if locomotor activity is affected by thetreatment, p=0.980
e. In which test is the strongest evidence for rejecting thenull found? The weakest? f. How do your answers to parts a-d changeif the researchers make their conclusions using a stricter 1%significance level?
