2. The engineering department at Simms Software Inc. recently developed two chemical solutions designed to increase the usable life of computer disks. The data for the two solutions is summarized in the following table: Solution 1 X=83.8 S1 = 13.68 n1 = 10 Solution 2 X=79.3 S2 = 6.71 n2 = 14 At the .10 significance level, can we conclude that there is a difference in the length of time the two types of treatment lasted
