The average age of a vehicle registered in the U.S. is 96 months. Assume the standard deviation is 16 months. If a random sample of 36 vehicles is selected, find the probability that the mean of their age is between 90 and 100 months. The average age of a vehicle registered in the U.S. is 96 months. Assume the standard deviation is 16 months. If a random sample of 36 vehicles is selected, find the standard error of the mean. The heights of the kindergarten children are approximately normally distributed with a population mean of 39 inches and a population standard deviation of 2 inches. A classroom of 30 of these kindergarten children is used as a sample. What is the probability that the class mean x bar is greater than 40 inches?
