It currently takes users a mean of 13 minutes to install the most popular computer program made by RodeTech, a software design company. After changes have been made to the program, the company executives want to know if the new mean is now different from 13 minutes so that they can change their advertising accordingly. A simple random sample of 37 new customers are asked to time how long it takes for them to install the software. The sample mean is 12.0 minutes with a standard deviation of 2.7 minutes. Perform a hypothesis test at the 0.10 level of significance to see if the mean installation time has changed. Step 1 of 3: State the null and alternative hypotheses for the test.

A simple random sample of 37 new customers are asked to time how long it takes for them to install the software. The sample mean is 12.0 minutes with a standard deviation of 2.7 minutes. Perform a hypothesis test at the 0.10 level of significance to see if the mean installation time has changed. Step 3 of 3: Draw a conclusion and interpret the decision. Answer Tables Keypad Keyboard Shortcuts We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.10 level of significance that the new mean installation time is different from 13 minutes and that RodeTech may need to change their advertising. We reject the null hypothesis and conclude that there is sufficient evidence at a 0.10 level of significance that the new mean installation time is different from 13 minutes and that RodeTech may need to change their advertising. We reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance that the new mean installation time is different from 13 minutes and that RodeTech may need to change their advertising. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance that the new mean installation time is different from 13 minutes and that RodeTech may need to change their advertising.
