You have a dataset of the average number of chirps per minute
for a sample of 30 crickets. You find that the mean number of
chirps per minute is 40 and that the number of chirps per minute
has a standard deviation of 5 chirps. You want to test that the
mean number of chirps per minute for a cricket is greater than 38
using a significance level of .05. What is the value of your test
statistic? Round your...
