A salesman for a new manufacturer of cellular phones claims not only that they cost the retailer less but also that the percentage of defective cellular phones found among his products, ( p1�1 ), will be no higher than the percentage of defectives found in a competitor's line, ( p2�2 ).

The retailer found that 66 of the salesman's cellular phones and 55 of the competitor's cellular phones were defective. Does the retailer have enough evidence to reject the salesman's claim? Use a significance level of α=0.01�=0.01 for the test. Step 4 of 6 : Compute the value of the test statistic. Round your answer to two decimal places
