The life of Sunshine CD players is normally distributed with a mean of 4.1 years and a standard deviation of 1.3 years. A CD player is guaranteed for three years. We are interested in the length of time a CD player lasts. Find the probability that a CD player will last between 2.8 and seven years. (a) Sketch the situation. Label and scale the axes. Shade the region corresponding to the probability. X X O 0.2 1.5 2.8 4.1 5.4 6.7 8 O 0.2 1.5 2.8 4.1 5.4 6.7 8 X X O 0.2 1.5 2.8 4.1 5.4 6.7 8 O 0.2 1.5 2.8 4.1 5.4 6.7 8 (b) Give the probability statement and the probability. (Enter exact numbers as integers, fractions, or decimals for the probability statement. Round the probability to four decimal places.)
