Question

You wish to test Ho: 5 against the alternative HA: 5. You collect a sample of N 90 observations and calculate Y-5.1 and s 1. Using the Minitab command Stat Basic Statistics 1 sample t, test the hypothesis at the 5% significance level. When using this command, you should click on the button for "summarized data. Click on the box "Perform hypothesis test." Your hypothesized value is 5.0. Click on options to make sure you have the right confidence level 100% significance level 95%). Put the test statistic (labeled Tin the Minitab output) in Blank 1 (two decimal places) and the p-value in Blank #2 (3 decimal places). Should we reject Ho? Yes or no, Blank #3. The test statistic that Minitab calculates for you is equal to: T Ex-H Blank 1 Blank a 2 Blank 3

Explanation / Answer

test stat = (5.1 - 5)/(1/sqrt(90)) = 0.95

p value = 0.34

Since p value > 0.05 we should not reject the Null Hypothesis - Ans) No
