Find the mean of the data summarized in the given frequency distribution. 1) The manager of a bank recorded the amount of time each customer spent waiting in line during pea 1) business hours one Monday. The frequency distribution below summarizes the results. Find the mei waiting time. Round your answer to one decimal place. Waiting time Number of (minutes) | customers 0 - 3 4- 7 11 8 - 11 13 12 - 15 16 - 19 20 - 23 24 - 27 A) 9.9 min B) 7.0 min C) 13.5 min D) 9.7 min Solve the problem. 2) At the U.S. Open Tennis Championship a statistician keeps track of every serve that a player hits 2) during the tournament. The statistician reported that the mean serve speed was 100 miles per hour (mph) and the standard deviation of the serve speeds was 15 mph. Assume that the statistician also gave us the information that the distribution of serve speeds was mound-shaped and symmetric. What percentage of the player's serves were between 115 mph and 145 mph? A) at most 13.5% B) at most 34% C) approximately 16% D) at most 2.5% Find the percentile for the data point. 3) Data set: 58 32 33 74 70 72 33; 3) data point 58 A) 57 B) 43 C) 20 D) 50 Solve the problem. 4) At the U.S. Open Tennis Championship a statistician keeps track of every serve that a player hits 4) during the tournament. The statistician reported that the mean serve speed of a particular player was 101 miles per hour (mph) and the standard deviation of the serve speeds was 11 mph. If nothing is known about the shape of the distribution, give an interval that will contain the speeds of at least eight-ninths of the player's serves. A) 134 mph to 167 mph B) 79 mph to 123 mph C) 68 mph to 134 mph D) 57 mph to 145 mph Find the indicated measure. 5) The weights (in pounds) of 30 newborn babies are listed below.
