15.) The mean wingspan for the population of a species of bird is known to be 30 inches, and the standard deviation for the wingspan of the population of the species of bird is known to be 4 inches. A researcher believes that the mean wingspan is actually less. He measures the wingspan of a sample of 10 birds, and finds that the mean wingspan of the birds in the sample is 28 inches. For a = 0.01 decide whether the mean wingspan is actually lower. a. State the null hypothesis and the alternative hypothesis. b. Is the test left-tailed, right-tailed, or two-tailed? c.
