Question

During the off-season (January – October), animal scientists at the North Pole train the reindeer to improve their take-off speed. During the most recent off-season, a new training device was used to improve the average time required for reindeer to sprint 200 yards. Each of the current reindeer was timed in the 200-yard dash before and after using the device. Using the data, the animal scientists wish to test the following hypotheses using a level of significance of 0.05.

Note that mu1 denotes the average time required for an untrained reindeer to sprint 200 yards and mu2 denotes the average time required for a trained reindeer to sprint 200 yards. Suppose data (time before training, time after training) are collected from 9 different reindeer and the resulting test statistic is zero.

Compute the P-value for this test.  (Report answer to three decimal places. Answer must be within +/- 0.001 of correct value.)

Explanation / Answer

as it is right tailed test ; therefore for test stat 0; p value is the are to the right half of curve.

hence p value =0.5000
