The distribution of blood pressure in healthy adult humans can be approximated by the Normal distribution with a mean of 85 mm and a standard deviation of 20 mm. A study is being planned that will involve a simple random sample of size 40 from the population of healthy adult humans. (a) What is the sampling distribution of ?̅? (b) What is the probability that the sample mean will be less than 75 mm? Round to four decimal places. Round to four decimal places. (c)Find the 80th percentile of the distribution of the average of these 40 blood pressure readings. Round to two decimal places.
