12) In an experiment with a certain mutation in the fruit fly Drosphila, n individuals were examined and 40% were found to mutants. Note!! Use p~, not p^ for a better approximation for the standard error on the true proportion.
12.1c)Construct a 99.9% confidence interval on the population proportion of fruit flies that are mutant given a sample size of n = 30. Use the standard error you calculated in 12.1a in your calculation. The answer is evaluated at third decimal accuracy. lower bound =? upper bound=?
12.1d)Construct a 99.9% confidence interval on the population proportion of fruit flies that are mutant given a sample size of n = 50. Use the standard error you calculated in 12.1b in your calculation. The answer is evaluated at third decimal accuracy. Lower bound =? Upper bound=?
