Chapter 12, Problem 6PT

To determine

To find: that is a valid representation of the result if the P-value given for the test is 0.0087.

Answer to Problem 6PT

If there is no relationship between average number of putts per hole and total winnings for the players on the PGA Tour’s world money list. The probability of getting a random sample of 69 players that yields a least-squares regression line with a slope of —4139198 or less is 0.0087.

Explanation of Solution

Given:

  

  $\begin{array}{c}{H}_0:\beta =0\\ H_1:\beta <0\end{array}$

If the null hypothesis is valid, the P-value is the likelihood of achieving the significance of the test results, or a value more extreme. The argument is about a population and NOT about a sample.

Hence, the correct option is (d)
