The average length of corn snakes in Okoboji is supposedly 20 inches and the standard deviation is known to be 3.3 inches. The distribution is normal. You take a simple random sample of 10 corn snakes and find the mean length in the sample is 22 inches and note that none of your snakes is less than 21 inches long. Test the hypothesis that, at the 2% level of significance, the average length of snakes in Okoboji is more than 20 inches.
