Use the Following Information to Answer the Question -Choose the Correct Null and Alternative Hypothesis to Test Whether

Multiple Choice

Use the following information to answer the question. A humanities professor is interesting in learning whether there is a
positive association between average online homework scores and the final class average in an online humanities course. The
computer output below shows the results from a regression model in which the final class average was predicted by the
average online homework score. Assume that the conditions of the linear regression model are satisfied. $$\begin{array} { | l l | } \hline { \text { LinRegTTest for } y = a + b x } \\\hline \beta > 0 & a = - 11.15986949 \\t = 8.285803594 & b = 1.111745514 \\p = 2.0898031 E - 4 & s = 4.349532611 \\d f = 124 & r = .9654613007 \\\hline\end{array}$$
-Choose the correct null and alternative hypothesis to test whether there is an association between final class average and average online homework scores.

A) $\mathrm { H } _ { 0 }$ : The correlation is positive.
$\mathrm { H } _ { \mathrm { a } }$ : The correlation is zero.
B) $\mathrm { H } _ { 0 }$ : There is no linear association between the final class average and the average online homework score.
$\mathrm { H } _ { \mathrm { a } }$ : There is a positive linear association between the final class average and the average online homework score.
C) $\mathrm { H } _ { 0 }$ : There is a linear association between the final class average and the average online homework score.
$\mathrm { H } _ { \mathrm { a } }$ : There is no linear association between the final class average and the average online homework score.
D) None of these.
