Let x be a random variable that represents hemoglobin count (HC) In grams per 100 milliliters of whole blood. Then x has a distribution that Is approximately normal, with population mean of about 14 for healthy adult women. Suppose that a female patient has taken 10 laboratory blood tests during the past year. The HC data sent to the patient's doctor are as follows. 16 18 16 18 13 13 14 16 17 11 LA USE SALT (a) Use a calculator with sample mean and standard deviation keys to find x and s. (Round your answers to two decimal places.) X = S (b) Does this information indicate that the population average HC for this patient is higher than 147 Use a = 0.01. (1) What Is the level of significance? State the null and alternate hypotheses. Hot H = 14; H1: H > 14 O Hoi H = 14; Him $ 14 OHOH = 14; Hip 14; He p = 14 OH: M
