1. The distribution of body sizes (in g) of wild mosquitoes breeding in the Back Bay Fens was sampled. Fifteen male mosquitoes were weighed, with the following results. Are they larger than the typical male (1.3 g)?

1.60, 1.61, 1.07, 1.34, 1.45, 1.43, 1.16, 2.11, 1.77, 1.08, 1.79, 1.07, 1.59, 2.07, 0.85

  1. What is the appropriate test to use for these data? Justify your answer.
  2. Test the hypothesis that these mosquitos are significantly larger than the typical male of the species. Let a = 0.05.
  3. What is the 95% confidence interval for the mean based on this sample?
