Read all directions carefully. Unless otherwise indicated, round your only nal answers to two decimal places. There is hint given for problems you might want to use. Problem #9. The average number (average number means mean) of pounds of meat that a person consumes a year is 218.4 pounds. Assume that the standard deviation is 25 pounds, and the distribution is approximately normal. If a sample of 40 individuals is selected, nd the probability that the mean of the sample will be less than 224 pounds per year. Show all your steps. Hint: use the formula for 2 Problem #10. Aresearcher tests the braking distances of several cars. The braking distance from 60 miles per hour to a complete stop on dry pavement is measured in feet. The braking distances of a sample of cars are normally distributed, with a mean of 129 feet and a standard deviation of 5.18 feet. What is the longest braking distance one of these cars could have and still be in the bottom 1%
