Question





The manufacturer of Brand A automobile tires claims that its tire can save 110 gallons of fuel over 55,000 miles of driving, as compared to a popular competitor (Brand B). If gasoline costs $4.00 per gallon, how much per mile driven does this tire save the customer (Brand A versus Brand B)?

Answer #1

Answer : For Brand A;

55,000 miles of driving saves 110 gallons of fuel

So, 1 mile of driving saves = 110 / 55,000 = 0.002 gallon of fuel.

Given, 1 gallon's cost is $4

So, 0.002 gallon's cost = 4 * 0.002 = $0.008

Therefore, Brand A automobile tires saves $0.008 for customer's per mile driven in compared to Brand B automobile tires.

    2.A tire manufacturer claims that the lifetime of its tires are normally distributed with a mean of m = 34,000 miles and a standard deviation of σ = 1200 miles. A trucking firm using these tires suspects that the mean lifetime is less than 34,000 miles. To test the claim, the firm randomly selects and tests 54 of these tires and gets a mean lifetime of 33,390 miles. Use a significance level of a = 0.05 to test the trucking...

    Stan Moneymaker has been informed of a major automobile manufacturer?s plan to conserve on gasoline consumption through improved engine design. The idea is called engine displacement, and it works by switching from 8-cylinder operation to 4-cylinder operation at approximately 40 miles per hour. Engine displacement allows enough power to accelerate from a standstill and to climb hills while also permitting the automobile to cruise at speeds over 40 miles per hour with little loss in driving performance. The trade literature...
