A tire manufacturer has a 60,000 mile warranty for tread life. The Select one answer manufacturer considers the overall tire quality to be acceptable if less than 5% 10 points are worn out at 60,000 miles. The manufacturer tests 250 tires that have been used for 60,000 miles. They find that 3.6% of them are worn out. With this data, we test the following hypotheses. H : The proportion of tires that are worn out after 60,000 miles is equal...
