In a test of hypothesis, the null hypothesis is that the population mean is greater than or equal to 41 and the alternative hypothesis is that the population mean is less than 41. The population has a normal distribution with standard deviation of 4.9. The test is to be made at the 3% significance level. A sample of size 37 is selected from this population. The approximate value of power at μ = 40.44 is O b. 0.0300 O c. 0.8821 O e. 0.1179 a. 0.0050 O d. 0.4227
