The average age of a vehicle registered in the U.S. is 96 months with a standard deviation of 10 months. If a random sample of 36 cars is selected, what is the probability that the mean of their age is between 96 and 100 months?

The average age of a vehicle registered in the United States is 8 years, or 96 months. If a random sample of 36 vehicles is selected, find the probability that the mean of their age is between 98 and 100 months? Assume the standard deviation for the population is 15. Label the normal curve and shade in the correct area desired
