The manufacturer of a new racecar engine claims that the proportion of engine failures due to overheating for this new engine, (p1), will be no higher than the proportion of engine failures due to overheating of the old engines, (p2). To test this statement, NASCAR took a random sample of 205 of the new racecar engines and 155 of the old engines. They found that 24 of the new racecar engines and 8 of the old engines failed due to overheating during the test. Does NASCAR have enough evidence to reject the manufacturer's claim about the new racecar engine? Use a significance level of α=0.05 for the test. Step 3 of 6 : Compute the weighted estimate of p, p‾‾. Round your answer to three decimal places.
