Question

10. (12 Points) Let x be a random variable that represents the hemoglobin count (HC) in human blood (measured in grams per milliliter). In healthy adult females, x has an approximately normal distribution with a population mean of mu = 14.0 and a population standard deviation of sigma = 2.3. Suppose that a female patient had 10 blood tests over the past year, and the sample mean HC was determined to be ar{x} = 15.3. With a level of significance alpha = 0.05, determine whether the patient's HC is higher than the population average. Specifically, do the following: a. (6 Points) Write the data and state the null hypothesis H_0 and the alternate hypothesis H_1. b. (3 Points) Show work to find the P-value.
