Pleаse nоte thаt this questiоn cоnsists of six pаrts. You may use MINITAB to double check your final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question. A tire manufacturing company claims that a particular brand of tire has an average life time for 60000 miles. Recently, the company has been getting many complaints from the consumers. Company would like to see if the true average lifetime of tires of that brand could possibly be well short of their quoted claim. They have collected data from a random sample of 36 tires of that particular brand manufactured by their company. Average lifetime for the sampled tires was 55200 miles with a standard deviation 9500 miles. Set up the appropriate null and alternative hypotheses for testing the company’s question to address the customer complaints. Make sure to use proper notations when setting up and . Are the conditions to carry out the above stated test are satisfied? If the conditions are satisfied, explain how they were satisfied for this problem rather than simply giving a "yes" or "no" answer. Calculate the test statistic. Show your calculations. Calculate the p-value for the test. You may use MINITAB to find the numerical value of the p-value for the test. However, you MUST clearly write down the probability statement. Write the final conclusion in the context of the problem (use 5% significance level). Instead of doing the above hypothesis test, suppose the company wanted to obtain an interval estimation for the true proportion of tires that does not last for 60000 miles. In the sample of 36 vehicles, lifetime of the tires were less than 60000 miles for 14 tires. Obtain a 90% confidence interval for the true proportion of tires that last for less than 60000 miles.
