(I got a t value od 1.8856)
Sportscasters are interested in whether professional golfers play better in their first round. Consider the following data. Let B=score in the final round of a professional golf tournament and A=score in the first round of a professional golf tournament. A random sample of 5 finalists in the British Open had the following data:
|
Player |
B (last round) |
A (first round) |
|
1 |
73 |
66 |
|
2 |
68 |
70 |
|
3 |
73 |
64 |
|
4 |
71 |
71 |
|
5 |
71 |
65 |
Do the data indicate that the population mean score on the last round is higher than that on the first round? Use a 5% level of significance.

College algebra students believe that the mean score on the first weekly test is 73. A statistics instructor thinks the mean score is higher than 73. He samples ten statistics students and obtains the scores 70; 65; 73; 68; 81; 82; 71; 67; 74; 82. He performs a hypothesis test using a 5% level of significance. The data are assumed to be from a normal distribution. a) Use a calculator function (Ttest / Ztest) to compute the p-value. (5 points)...
