7. The new 'Tigercat' sports car has an idle loping problem as about10 per cent of the Tigercats have an unstable fluctuating engine speedwhen they are idling. An engineering 'fix' is put in a production pilotlot of a hundred cars.(a) If the fix has no effect on the problem, how many cars would youexpect to have the fault?(b) If only two of the pilot lot have the idling fault, and the otherninety-eight cars are not defective, would you conclude that the fix hasa significant effect? (Hint: Show that the probability of getting two orless defectives in a sample size of a hundred, given that the fix has noeffect, is very small indeed.)

Given: Total cars n=100 Defect probability is 10%

Answered: 7. The ne idle loping problem as about…

Suppose Aaron recently purchased an electric car. The person who sold him his new car told him that he could consistently travel 200 mi before having to recharge the car's battery. Aaron began to believe that the car traveled even farther than the company claimed, and he decided to test this hypothesis formally. Aaron drove his car only to work and he recorded the number of miles that his new car traveled before he had to recharge its battery a total of 17 separate times.
