In a test of hypothesis, the null hypothesis is that the population mean is greater than or equal to 37 and the alternative hypothesis is that the population mean is less than 37. The population has a normal distribution with variance of 10.6. The test is to be made at the 5% significance level. In order that the value of power at M₁ = 35. 27 to be 0.9, how large a sample do we need? O d. 20 O e. 38 O c. 6 O a. 31 O b. 63
