Question

A quality control supervisor selected a sample of 100 electronic components from each of three different production chains to determine if the production chains had the same rates of meeting their quality standards. At = .05, test the claim that the proportions are equal.

Components	Chain 1	Chain 2	Chain 3
Meets the standard	76	85	71
Does not meet the standard	24	15	29
Total	100	100	100

	A.	There is evidence to reject the claim that the proportions are equal because the test value 5.743 < 5.991
	B.	There is evidence to reject the claim that the proportions are equal because the test value 5.991 > 5.743
	C.	There is not evidence to reject the claim that the proportions are equal because the test value 5.743 < 5.991
	D.	There is not evidence to reject the claim that the proportions are equal because the test value 5.991 > 5.743
