It currently takes users a mean of 5 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 5 minutes so that they can change their advertising accordingly. A simple random sample of 46 new customers are asked to time how long it takes for them to install the software. The sample mean is 4.7 minutes with a standard deviation of 1.1 minutes. Perform a hypothesis test at the 0.10 ievel 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 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 5 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 5 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 5 minutes and that RodeTech may need to change their advertising. 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 5 O minutes and that RodeTech may need to change their advertising.
