160 students who were majoring in either math or English were asked a test question,and the researcher recorded whether they answered the question correctly.The sample results are given below. $4337\begin{array} { r | c c } & \text { Correct } & \text { Incorrect } \\\hline \text { Math } & 27 & 53 \\\text { English } & 43 & 37\end{array}$ $x ^ { 2 }$ = 6.502; P-value = 0.011 Are the response and major independent? Use a 5% level of significance.

A) Report that the distribution of correct answers is uniform for both majors because the null hypothesis is rejected.
B) Report that response is not dependent on major because the null hypothesis is rejected.
C) Report that response is not dependent on major because the null hypothesis is not rejected.
D) Report that response is dependent on major because the null hypothesis is rejected.

Question

160 students who were majoring in either math or English were asked a test question,and the researcher recorded whether they answered the question correctly.The sample results are given below.

4337\begin{array} { r | c c } & \text { Correct } & \text { Incorrect } \\\hline \text { Math } & 27 & 53 \\\text { English } & 43 & 37\end{array}

x ^ { 2 }

= 6.502; P-value = 0.011 Are the response and major independent? Use a 5% level of significance.

A) Report that the distribution of correct answers is uniform for both majors because the null hypothesis is rejected.
B) Report that response is not dependent on major because the null hypothesis is rejected.
C) Report that response is not dependent on major because the null hypothesis is not rejected.
D) Report that response is dependent on major because the null hypothesis is rejected.
E) Report that response is dependent on major because the null hypothesis is not rejected.

Final Answer : D, Explanation :  The null hypothesis in this case is that the response (correct/incorrect) is independent of the major (math/English). Since the P-value is less than the significance level of 5%, we reject the null hypothesis. This means that we have evidence to suggest that there is a relationship between the response and major, and therefore the response is dependent on major. Choice D is the statement that reflects this conclusion.
