T10.12. A random sample of 100 of a certain popular carmodel last year found that 20 had a certain minor defectin the brakes. The car company made an adjustment inthe production process to try to reduce the proportion of cars with the brake problen. A random sample of 350 ofthis year's model found that 50 had the minor brake defect.(a) Was the company's adjustment successful? Carry outan appropriate test to support your answer.(b) Describe a Type I error and a Type II error in thissetting, and give a possible consequence of each.
