Chapter 12, Problem T12.5SPT

To determine

To find out by which of the following is the value of the t statistic for this test.

Answer to Problem T12.5SPT

Option (d) is the correct option.

Explanation of Solution

It is given that the good putting is more important than long driving for shooting low scores and hence winning money. To see if this is the case, then the random sample of players are selected for examining. They have assumed that the inference conditions about the slope are met and the data is calculated by the computer output is given in the question. Suppose the researcher test the hypothesis. Thus, it is given that

  $\begin{array}{l}b=-4139198\\ S{E}_{b_1}=1698371\\ H_0:\beta =0\\ H_1:\beta <0\end{array}$

Thus, we compute the value of test statistics as:

  $\begin{array}{l}t=\frac{b-{\beta }_0}{S{E}_{b_1}}\\ =\frac{-4139198-0}{1698371}\\ \approx -2.44\end{array}$

Thus, the option (d) is the correct option.
