Q2: suppose that X,., X, a random sample of size n from the normal distribution N(u,02), where the mean u is unknown. In testing Ho : o? = 03 against H, : o? > o3, use the critical region defined by (n – 1)s /03 2 c. That is, reject H, and accept H, if S? > co3/(n – 1), where S? the variance of a random sample of size n. Let n = 13 and the significance level a = 0.025.

Q2: suppose that X,.., X, a random sample of size n from the normal distribution N(u,02), where the mean u is unknown. In testing Ho : o2 = o against H, : o? > o, use the critical region defined by (n - 1)s² /o > c. That is, reject Ho and accept H, if S2 2 co/(n – 1), where S? the variance of a random sample of size n. Let n = 13 and the significance level a = 0.025. 3. The value of the power is given by A. 0.025
