Question

on part 3 choose W, X, Y, Z in choices

A random sample of 100 pumpkins to be used for Halloween Jack-O-Lanterns is obtained and the mean circumference is found to be 40.5 cm. Assuming that the population standard deviation o is known to be 1.6 cm, use a 0.05 significance level to test the claim that the mean circumference of all such pumpkins is significantly different from 39.9 cm. Part I. Which of the following is the appropriate set of null and alternative hypotheses? [Select] A. Ho = 39.9 vs Ha: 39.9 B. Ho : X = 39.9 vs Ha: X 39.9 C. Ho = 40.5 vs Ha: 40.5 D. Họ : X = 40.5 vs Ha : X # 40.5 Part II. What is the computed value of the test statistic? [Select] > Part III. What conclusion may be drawn? [Select] W. There is sufficient evidence to reject Ho. The mean circumference of pumpkins differs significantly from the hypothesized mean circumference value. > X. There is insufficient evidence to reject Ho. The mean circumference of pumpkins does not differ significantly from the hypothesized mean circumference value. Y. There is sufficient evidence to reject Ho. The mean circumference of pumpkins does not differ significantly from the hypothesized mean circumference value. Z. There is insufficient evidence to reject Ho. The mean circumference of pumpkins differs significantly from the hypothesized mean circumference value.
