A population of values has a normal distribution with = 91.7 and = 31.3. If a random sample of size n = 14 is selected, a. Find the probability that a single randomly selected value is greater than 65.8. Round your answer to four decimals. P(X>65.8) b. Find the probability that a sample of size n=14 is randomly selected with a mean greater than 65.8. Round your answer to four decimals. P(M> 65.8) = A population of values has a normal distribution with μ-100.1 and 60.8. A random sample of size n 166 is drawn. a. What is the mean of the distribution of sample means? b. What is the standard deviation of the distribution of sample means? Round your answer to two decimal places. σ A population of values has a normal distribution with = 91.7 and = 31.3.
