A researcher was interested in comparing the salaries of female and male employees at a particular company. Independent simple random samples of 8 female employees and 15 male employees yielded the following summary statistics for weekly salaries (in dollars): X1 = 701.375, X2 = 812.067, s1 = 184.855, s2 = 332.146.

Determine a 98% confidence interval for the difference, u1 − u2, between the mean weekly salaries of female employees and the mean weekly salaries of male employees at this particular company. (Assume that o1≠ o1).
