**** need equations and calculations please**** NEED SOON !!!! One of the important factors in auto safety is the weight of the vehicle. Insurance companies are interested in knowing the average weight of cars currently licensed in the United States; they believe it might be 3000 pounds. To see if that estimate is correct, they hire you to do a 95% confidence interval. You randomly sample a group of 41 cars and find a mean weight of 2959 pounds with a standard deviation of 551.5 pounds. Construct a 95% confidence interval. What will you report to your client about their belief based on your interval?
