Give the plus four 95% confidence interval for the proportion of heterozygotes in the population of red-eyed fruit flies studied.

How many red-eyed fruit flies should be used in this experiment to obtain a 95% confidence interval with a margin of error no more than 3%? Use 20% as a conservative (worst-case) estimate of the percent of heterozygotes in the population.

The P-value for the test is
