Following are heights, in inches of 10 boys, measured at age 12 and again at age 14. Age 12: 59.7, 56.3, 63.0, 58.6, 61.1, 59.5, 61.6, 59.3, 62.1, 62.8. Age 14: 65.4, 61.5, 68.5, 63.9, 65.8, 64.5, 66.3, 64.2, 67.1, 68.1. Construct a 98% confidence interval for the mean increase in height for boys between the age of 12 and 14. Let d represents the height at age 14 minus the height at age 12. Use the ti 84 calculator to find the critical value and round the answers to at least two decimal places. A 98% confidence interval for the mean increases in height for boys between 12 and 14 is ?
