The hemoglobin count (HC) in grams per 100 milliliters of whole blood is approximately normally distributed with a population mean of 14 for healthy adult women. Suppose a particular female patient has had 11 laboratory blood tests during the past year. The sample readings showed an average HC of 14.65 with a standard deviation of 2.15. Does it appear that the population average HC for this patient is not 14? (a) State the null and alternative hypotheses: (Type "mu" for the symbol μ, e.g. mu> 1 for the mean is greater than 1, mu< 1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1) Ho: HA: (b) Find the test statistic, t =
