Medical: Hemoglobin Count 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 (see reference in Problem 17). 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 15 18 16 19 14 12 14 17 15 11 i. Use a calculator with sample mean and sample standard deviation keys to verify that x 5 15.1 and s < 2.51.

ii. Does this information indicate that the population average HC for this patient is higher than 14? Use a 5 0.01.
