Keyless entry clickers are used to open doors in a variety of products. Suppose you are a quality control statistician responsible for monitoring the manufacturing of your company's newest entry clicker. The mean target activation force for the button on the clicker is 1.97 newtons. Too much force makes the keys hard to click, while too little force means the keys might be clicked accidentally. To check the mean force on the newest production batch, you sample 16 clickers. The mean and standard deviation from the sample equals 1.88 newtons and 0.145 newtons respectively. A. Perform the appropriate test at alpha = .05 to determine if the clickers are meetings the target activation force. Make sure that you include all required steps of the hypothesis testing procedure as outlined in class. B. Construct a 95% confidence interval estimate for the mean force. Explain how the confidence interval supports your conclusion for the hypothesis test.
