The production manager of a large manufacturing company estimates that the mean age of his workers is 22.8 years. The treasurer of the firm needs more accurate employees’ average age figure to estimate the cost of an annuity benefit program being considered for employees. The treasurer takes a random sample of 25 employees and finds that the mean age of the sampled employees is 26.2 years with a standard deviation of 4.6 years. At 99% confidence interval, test the hypothesis that the mean age of the employees is not equal to 22.8 years.
An industrial sewing machine uses ball bearings that are targeted to have a diameter of 0.75 inch. The lower and upper specification limits under which the ball bearings can operate are 0.74 inch and 0.76 inch, respectively.

The standard deviation of the textbook costs is below $30. B. The standard deviation of the textbook costs is larger than $100. C. A stem-and-leaf plot of the textbook costs shows a roughly symmetric distribution. D. A histogram of the textbook costs is calculated and shows a slight skew to the right. E. A boxplot of the textbook costs shows two students whose amounts would qualify as outliers.
