To find out which of the following is the
Answer to Problem T12.7SPT
Option (e) 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. The P-value of the test statistic is
The estimate of the slope
The estimated standard deviation of the slope
The critical t-value can be found in the Student’s T distribution table in the appendix in the row, then the degrees of freedom is:
Thus,
The boundaries of the confidence interval then become:
Thus, the option (e) is the correct option.
