13. Credit Rating When consumers apply for credit, their credit is rated using FICO

(Fair, Isaac, and Company) scores. Credit ratings are given below for a sample of applicants for car loans, and these applicants are all from a new branch of the Bank of Newport. Use the sample data to test the claim that these credit ratings are from a population with a standard deviation different from 83, which is the standard deviation for applicants from the main bank. Use a 0.05 significance level. Based on the results, do applicants from the branch appear to have credit ratings that vary more than those at the main bank?
