STAT 245 Lecture Notes - Lecture 46: Null Hypothesis, Minitab, Test Statistic
Document Summary
To replace the following: and the test statistic is z x. Since the p-value is less than . 05, the p null hypothesis is rejected . There is sufficient evidence to indicate that the average diameter of the tendon for patients with at is greater than 5. 97 mm. 9. 18 a-b the hypothesis of interest is one-tailed: 0 c the test statistic, calculated under the assumption that. 2. 09 a value which lies slightly more than two standard deviations from the hypothesized difference of zero. This would be a somewhat unlikely observation, if h0 is true. d the p-value for this one-tailed test is. , the null hypothesis cannot be rejected at the 1% level. 0 e using the critical value approach, the rejection region, with. Since the observed value of z does not fall in the rejection region, h0 is not rejected. 9. 21 a the hypothesis of interest is one-tailed: The test statistic, calculated under the assumption that.
