The average number of tadpoles per gallon of water in Rocky Mountain National Park is believed to be 13, and is normally distributed. You collect 10 one gallon samples and find the following numbers of tadpoles:

10, 13, 10, 11, 10, 20, 15, 21, 14, 16

From these, you calculate the mean to be 14 and the standard deviation to be 4.06. Test the hypothesis that, at the 6% level of significance, the mean number of tadpoles per gallon in Rocky Mountain National Park is different from 13.
