The seats were subjected to a safety stress test in which scores were assigned on a continuous scale of 0 to 10. This test was performed on a large sample of model C seats. The mean score was 6.8 with a standard deviation of 0.34. You may assume that the scores are normally distributed and the stated mean and standard deviation represent our best estimate of those population parameters.Suppose you select a sample of 5 seats subject each of them to the stress test and compute the mean score for the sample. What is the probability that the mean score will be less than 6.2?
