Question 12: In a recent article, a study of the failure pressures of roof panels were examined. The following are the failure pressures, in kPa, for five panels constructed with 6d smooth shank nails. 3.32 2.53 3.45 2.38 3.01 12. Find and interpret a 95% confidence interval for the mean failure pressure for this type of roof panel. Question 13-14: In a study of the relationship of the shape of a tablet to its dissolution time, 6 disk-shaped ibuprofen tablets and 8 oval-shaped ibuprofen tablets were dissolved in water. The dissolve times, in seconds, were reported. For the disk-shaped ibuprofen tablets, the average dissolve time was 255.8 seconds with a standard deviation of 8.2163. For the oval-shaped ibuprofen tablets, the average dissolve time was 270.9 seconds with a standard deviation of 11.7044. Assume the population variances are equivalent. 13. Can 1 conclude that the mean dissolve times differ between the two Use a = 0.05 14. If you want your ibuprofen to take effect as quickly as possible, do you want to take a disk-shaped or an oval-shaped tablet? (Circle one.) Disk-shaped Oval-Shaped
