Let X be hemoglobin count (HC) in grams per 100 m ers of whole blood for a healthy adult woman. it is belleved that X has a normal distribution with a mean or 14 and an unknown standard deviation, A random sample of ten healthy adult females was taken with the following HC for each:: 15,13,16,19, 14, 12, 14, 17.15.11 So, we assume that our sample comes from a normal population with unknown standard deviation of a. We would like to test whether the mean HC IS hlgher than 14. The null hypothesis is thus H0: =14 . We will test this against the alternative Ha. we want to test at the 1% level, Let; the sample mean and s = the sample standard deviation. a) What should the alternative hypothesis, Ha , be? Haio=14 Hazu>14 H51u (scar T > tstar/z or T tstar or T
