The heights of kindergarten children are approximately normally distributed with the following. (Give your answers correct to four decimal places.) μ = 35 and σ = 3.2 inches (a) If an individual kindergarten child is selected at random, what is the probability that he or she has a height between 32.8 and 37.2 inches? (b) A classroom of 25 of these children is used as a sample. What is the probability that the class mean x is between 32.8 and 37.2 inches? (c) If an individual kindergarten child is selected at random, what is the probability that he or she is taller than 36.5 inches? (d) A classroom of 25 of these kindergarten children is used as a sample. What is the probability that the class mean x is greater than 36.5 inches?
