Yumi reads that the average maple leaf is 5.5 inches in length. She believes the maple leaves growing on the trees in her yard are longer. She randomly selects 15 leaves from the trees and measures them. The sample mean is 5.65 inches with a sample standard deviation of 0.36 inches. Perform a significance test for the sample mean using a significance level of ? = 0 05.Since 1.559 -1.761, you reject the null hypothesis.
