The sample size is 17 and the value of the t-test statistic is 2.82. What is the P-value of the test? # between 0.05 and 0.10 %% between 0.025 and 0.05 %% between 0.005 and 0.01 %% between 0.01 and 0.02 %%|For a simple random sample of 25 employees of a university the average time these employees had worked for the university was 7 years with a sample standard deviation of 2 years. We want to test <img src="teststat71.jpg">. The test statistic is # -0.25 %% 0.25 %% -1.25 %% 1.25 %%|For a random sample of 25 employees of a university the average time these employees had worked for the university was 7 years with a sample standard deviation of 2 years. We want to test <img src="teststat71.jpg">. Based on this data we conclude that # we would not reject the null hypothesis at significance level 0.10. %% we would reject the null hypothesis at significance level 0.10 but not at 0.05. %% we would reject the null hypothesis at significance level 0.05 but not at 0.01. %% we would reject the null hypothesis at significance level 0.01 but not at 0.005. %%
