The article “Effects of Waste Glass Additions on the Properties and Durability of Fired Clay Brick” (S. Chidiac and L. Federico, Can J Civ Eng, 2007: 1458–1466) reports that the average initial rate of ab- sorption \(\text { (in } \mathrm{g} / \mathrm{min} \cdot \mathrm{cm}^{2} \text { ) }\) for a sample of five clay bricks with fine glass particles added was 1299.8 with a standard deviation of 329.8, and the average for a sample of five bricks without glass particles added was 4500.8 with a standard deviation of 271.6. Find a 98% confidence interval for the difference between the mean initial absorption rates.
