QUESTION 8 The production manager of a manufacturer wants to evaluate a modified ball bearing production process. When the process is operating properly, the process produces ball bearings whose weights have a mean of 5 ounces and a standard deviation of 0.1 ounce. A new raw-material supplier was used for a recent production run, and the manager wants to know if that change has caused any problem. If there was a problem, the mean weight of a ball bearing would be different. The manager will test the following hypotheses Ho:M = 5 and H1:H x 5 From a random sample of 100 ball bearings, the sample mean was 4.96. The significance level is specified as 10%. What is the probability of type l errors in this hypothesis testing? O a. 10.00% O b. 2.58% O C. 4.96% O d. 0.04% O e. 5.00% QUESTION 9 Click Save and Submit to save and submit.
