(1 point) 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 9 laboratory blood tests during the past year. Her average HC is 15.98 with s = 1.45. Is there evidence that her average HC is not 14? (a) State the null and alternative hypotheses: (Type "mu" for the symbol , 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, rounded to 3 decimal places, t = (c) Answer the question: Is there evidence that her average HC is not 14? (Use a 1% level of significance) (Type: Yes or No) Yes
