Extracted text: It currently takes users a mean of 16 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 16 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 17.1 minutes with a standard deviation of 3.6 minutes. Perform a hypothesis test at the 0.005 level of significance to see if the mean installation time has changed. Step 2 of 3: Compute the value of the test statistic. Round your answer to three decimal places. Answer 画 Tables 画 Keypad Keyboard Shortcuts
