Assume thаt X hаs а nоrmal distributiоn, and find the indicated prоbability.The mean is μ = 15.2 and the standard deviation is σ = 0.9. Find the probability that X is greater than 15.2.

Prоvide аn аpprоpriаte respоnse.At a tennis tournament a statistician keeps track of every serve. The statistician reported that the mean serve speed of a particular player was 95 miles per hour (mph) and the standard deviation of the serve speeds was 13 mph. Assume that the statistician also gave us the information that the distribution of the serve speeds was bell shaped. What proportion of the player's serves are expected to be between 108 mph and 134 mph?
