P-value for a left tailed test with a test-statistic of -1.15 from a sample of size 21.

Question

Quizplus · Accepted Answer

For a left-tailed test with a test statistic of -1.15 and a sample size of 21 (which gives us 20 degrees of freedom), the p-value indicates the probability of observing a result as extreme as, or more extreme than, the test statistic under the null hypothesis. Given the relatively small magnitude of the test statistic (-1.15), the p-value would be relatively large, indicating that the result is not highly unusual under the null hypothesis. Therefore, the p-value would be larger than 0.10, as more extreme negative values are needed to obtain smaller p-values in a left-tailed test.
