At a tennis tournament a statistician keeps track of every serve. The statistician reported the the mean serve speed of a particular player was 97 miles per hour (mph) and the standard deviation of the serve speeds was 11 mph. Assume that the statistician also gave us the information that the distribuation of the serve speeds was bell shaped. What percentage of the players serves are expected to be between 75mph and 130mph? a) there are TWO "k" values in this problem. _____ (blank) and ____ (blank). Remember that "k" is the number of standard deviations from the mean. b) the percentage of the players served betweeen 75 and 130 is ___ (blank)

Sarah and her fiancé are planning for their wedding. Distribution of the number of guests coming to the party is normal with the mean 100 and the standard deviation 10. They need to determine how many guests to book for food from a caterer. The caterer makes the following charges: $50 for each guest that is booked in advance; $90 for each guest who is not booked in advance but shows up on the wedding day.
