asic asic 5 16 A study is designed to test the hypotheses Ho 26 versus Ha 26 A random sample of 50 units was selected from a specified population and the measurements were summarized to y 25 9 and s 7 6 a With a 05 is there substantial evidence that the population mean is less than 26 b Calculate the probability of making a Type II error if the actual value of the population mean is at most 24 c If the sample size is doubled to 100 what is the probability of making a Type II error if the actual value of the population mean is at most 24 5 17 Refer to Exercise 5 16 Graph the power curve for rejecting Ho 26 for the following values of 20 21 22 23 24 25 and 26 a Describe the change in the power as the value of decreases from 40 26 b Suppose the value of n remains at 50 but a is decreased to a 01 Without recalculating the values of the power superimpose on the graph for a 05 and n 50 the power curve for a 01 and n 50 c Suppose the value of n is decreased to 35 but a is kept at a 05 Without recal culating the values of the power superimpose on the graph for a 05 and n 50 the power curve for a 05 and n 35
