When Connor was 16, he bought his first car. It had 1.67\times 10^{5}1.67×105miles on it. Connor is now 55 and wants to buy his dream car. He wants a new car or a used one with low miles. The car he ends up buying has 4.35\times 10^{3}4.35×103miles. How many times greater were the miles on his old car than his new car? Round to the nearest whole number.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
