In a test of hypothesis, the null hypothesis is that the population mean is less than or equal to 32 and the alternative hypothesis is that the population mean is greater than 32. The population has a normal distribution with variance of 12.5. The test is to be made at the 10% significance level. A sample of size 41 is selected from this population. The approximate value of 3 at μ = 32.35 is O a. 0.5403 O d. 0.7414 O e. 0.9000 O b. 0.2586 O c. 0.9723
