psychologist is studying the self image of smokers, as measured by the self-image (SI) score from a personality inventory. She would like to examine the mean SI score, u, for the population of all smokers. Previously published studies have indicated that the mean SI score for the population of all smokers is 80 and that the standard deviation is 12, but the psychologist has good reason to believe that the value for the mean has changed. She plans to perform a statistical test. She takes a random sample of SI scores for smokers and computes the sample mean to be 72 Based on this information, complete the parts below.

They measured the length of one tibia per mouse in mice randomly sampled from each line and recorded the genetic sex of each mouse. Keep in mind! Longer tibias have relation with longer legs.
