Refer to Exercise 9.6. You want to test H0: µ = 2.3 against Ha: µ > 2.3.
a. Find the critical value of used for rejecting H0.
b. Calculate ? = P(accept H0 when µ = 2.4).
c. Repeat the calculation of b for µ = 2.3, 2.5, and 2.6.
d. Use the values of ? from parts b and c to graph the power curve for the test.
Exercise 9.6
A random sample of n = 35 observations from a quantitative population produced a mean = 2.4 and a standard deviation s = .29. Suppose your research objective is to show that the population mean m exceeds 2.3.
