I need help finding the null and alternative hypothesis and the t- statistic please. Thanks!

(15 points) The hemoglobin count (H0) 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 15 laboratory blood tests during the past year. The sample readings showed an average HC of 18.09 with a standard deviation of 2.81. 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 ,u , e.g. mu > 1 for the mean is greater than 1, mu
