A Quality Control Supervisor Selected a Sample of 100 Electronic $= .05$

question 5

Multiple Choice

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
$\begin{array}{lccc}\text { Components } & \text { Chain 1 } & \text { Chain 2 } & \text { Chain ? } \\\text { Meets the standard } & 77 & 85 & 73 \\\text { Does not meet the standard } & 23 & 15 & 27 \\\text { Total } & 100 & 100 & 100\end{array}$

• A) There is evidence to reject the claim that the proportions are equal because the test value \(12.592 >\) \(0.786\)
• B) There is not evidence to reject the claim that the proportions are equal because the test value \(4.399 <\) \(5.991\)
• C) There is evidence to reject the claim that the proportions are equal because the test value \(5.991 > 0.786\)
• D) There is evidence to reject the claim that the proportions are equal because the test value \(4.399 < 5.991\)
