To test Ho: μ = 105 versus H₁: μ#105 a simple random sample of size n = 35 is obtained. Complete parts a through e below. Click here to view the t-Distribution Area in Right Tail. (a) Does the population have to be normally distributed to test this hypothesis? Why? O A. No, because the test is two-tailed. OB. No, because n ≥ 30. OC. Yes, because n ≥ 30. OD. Yes, because the sample is random.
