The scores on a test for children in an eighth-grade class is normally distributed with a mean of 73 and a standard deviation of 5.7. Answer the following: a) What is the probability a test score is less than 82? b) Pearl E. Gates has a test score called S. If another child in the class is picked at random, the probability that the other child has a score higher than Pearl is 0.48. Find Pearl’s test score.
