The hemoglobin count (HC) in grams per 100 milliliters of whole blood is approximately normally distributed with population mean 14 for healthy adult women. Suppose a female patient has had 16 laboratory blood tests during the past year. Her average HC is 16.94 with s = 1.05. Is there evidence that her average HC is not 14? (a) State the null and alternative hypotheses: (Type "mu" for the symbol µ, eg. 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) Но: На (b) Find the test statistic (give to at least 3 decimal places), t =
