Suppose that the weight of crows is normally distributed with a standard deviation of 5. You are walking down the street and sample 9 crows from this population and obtain a mean weight of 28.95 and a standard deviation of 6.3802. Using an alpha value of = 0.01, is this observed mean significantly different than the expected weight of the crow is 27? (Hint: Its two-tailed test) (Write Y is significantly different and N if not significantly different)
