I acquire some assistance! If you may show work for both that'd be excellent

A consumer report claims that more than 10% of the cars from a car manufacture experience engine failures before reaching a mileage of 150,000 miles. A sample of 65 cars is investigated and 9 of the cars had engine failure before 150,00 miles. Conduct a hypothesis test to test the claim with a significance level of 0.10. You must show all the detailed work for the 4 steps (null and alternative hypothesis, calculation, comparison, conclusion) introduced in the instructor's videos (chapter 8). No work or little work will result in no credit or little credit. The Department of Transportation of the State of New York claimed that it takes an average of 200 minutes to travel by train from New York to Buffalo. A random sample of 40 trains was taken and the average time required to travel from New York to Buffalo was 188 minutes, with a standard deviation of 28 minutes. Conduct a hypothesis test to test the claim with a significance level of 0.01. You must show all the detailed work for the 4 steps (null and alternative hypothesis, calculation, comparison, conclusion) introduced in the instructor's videos (chapter 8). No work or little work will result in no credit or little credit
