From past experience, she has found that the reviews take her approximately four hours each to do with a population standard deviation of 1.2 hours. Let Χ be the random variable representing the time it takes her to complete one review.Assume Χ is normally distributed.Let be the random variable representing the mean time to complete the 16 reviews. Assume that the 16 reviews represent a random set of reviews.

A. Find the probability that the mean of a month’s reviews will take Yoonie from 3.5 to 4.25 hrs. Sketch the graph, labeling

and scaling the horizontal axis. Shade the region corresponding to the probability.

b. P(________________) = _______

C. Find the 95th percentile for the mean time to complete one month’s reviews. Sketch the graph.
