Multiple choice: Select the best answer for Exercises 95 to 102. You are testing H0 :m = 10 against Ha :m 10 based on an SRS of 15 observations from a Normal population. What values of the t statistic are statistically significant at the a = 0.005 level? (a) t > 3.326 (d) t < 3.326 or t > 3.326 (b) t > 3.286 (e) t < 3.286 or t > 3.286 (c) t > 2.977
ANSWER:Step 1 of 2
Given that,
The null hypothesis H0: = 10 against Ha : ? 10 is tested based on an SRS of n = 15 observations from a Normal population.
We need to determine the values of the t statistic that are statistically significant at the = 0.005 level. The options are provided as:
(a) t > 3.326
(b) t > 3.286
(c) t > 2.977
(d) t < ?3.326 or t > 3.326
(e) t < ?3.286 or t > 3.286
