The life of Sunshine CD players is normally distributed with mean of 3.6 years and a standard deviation of 1.1 years. A CD player is guaranteed for two years. We are interested in the length of time a CD player lasts. The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.5 Find the 70th percentile of the distribution for the time a CD player lasts. and a standard deviation of 1.9 days. (a) Select the correct graph for the situation with shading for the region corresponding to the percentile. (a) What is the median recovery time? 0 7.4 D 2.8 5.5 O 1.9 1. 2.
