Question

A limousine company is concerned with increasing costs of maintaining their fleet of 150 cars. After testing, the company found that the emissions systems of 17 out of the 29 cars they tested failed to meet pollution control guidelines. They had forecasted costs assuming that a total of 15 cars would need updating to meet the latest guidelines. Is this strong evidence that more than 10 % of the fleet might be out of compliance? Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed.

What is the P-value of the test statistic? A. P-valueequals nothing (Round to three decimal places as needed.)
