1. You are interested in whether the average lifetime of Duracell AAA batteries is less than the average lifetime of Energizer AAA batteries. You lay out your hypotheses as follows: Null Hypothesis: μ1 ≥ μ2, Alternative Hypothesis: μ1 < μ2 (Duracell = Group 1, Energizer = Group 2). You perform an experiment on 20 randomly selected Duracell AAA batteries and 40 randomly selected Energizer AAA batteries and test them using a battery drainer. The Duracells had an average lifetime of...

You are investigating the difference in weight gain between female and male iguanas when they are both given a high protein diet for a week. Each iguana in the study is to be matched with another iguana of opposite sex, of similar age and size. From similar studies done in the past, you know that female iguanas, on average, put on 2.5 more pounds of weight than male iguanas do post-diet. These studies also indicate that the standard deviation of...
