A blood plasma donation company accepts 40 volunteers per day; Based on previous data, they know that 15% of volunteers will be turned away for some reason: Let X represent the number of patients that get tumed away in a set of 40 volunteers FInd the mean and standard deviation of X You may round vour answers t0 the nearest tenth #X volunteers volunteers

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 a 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 20 15 12 15 16 16 10 (a) Use a calculator with sample mean and standard deviation keys to finding x and s. (Round your answers to two decimal places.) x=s=
