DO THE MATH AND READ THE TABLE NOT SOFTWARE. SKIP a

(b) IT ASKS FOR LESS THAN SO ITS THE VALUE (AREA) IN THE TABLE. CALUCLATE THE Z-SCORE AND READ THE AREA FROM THE TABLE (WHICH IS THE PROBABILITY OR PERCENTAGE BELOW 220).

(c) THE 80^THPERCENTILE SIMPLY MEANS 80% OF THE AREA (TO THE LEFT). THIS MEANS THAT 80% OF THE BASEBALLS TRAVEL LESS THAN THIS DISTANCE. FIND THE Z-VALUE CORRESPOINDING TO 0.80 IN THE TABLE AND BACK-CALCULATE THE X-VALUE (THE DISTANCE). NO SOFTWARE.

76. Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet anda standard deviation of 50 feet.a. If X = distance in feet for a fly ball, then X ~ _____(_____,_____)

b. If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than220 feet? Sketch the graph. Scale the horizontal axis X. Shade the region corresponding to the probability. Findthe probability.

c. Find the 80th percentile of the distribution of fly balls. Sketch the graph, and write the probability statement.
