Transcribed Image Text:Let x be a random variable that represents hemoglobin count (HC) in grams per 100 milliters 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 temale patient has taken 10 laboratory blood tests during the past year, The HC data sent to the patient's doctor are as follows.
