New tires manufactured by a company in Findlay, Ohio are designed to provide a mean of at least 28,000 miles. You believe that the actual mean mileage is less, and want to prove it. What hypotheses would you use to test if the data provide sufficient evidence to reject the claim of a mean of at least 28,000 miles?

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
