Suppose we have taken independent, random samples of sizes n1 = 7 and n2 = 7 from two normally distributed populations having means µ1 and µ2, and suppose we obtain  = 240,  = 210, s1 = 5, s2 = 6.

Assuming equal variances calculate a 95 percent confidence interval for µ1 − µ2. Can we be 95 percent confident that µ1 − µ2 is greater than 20? (Round your answers to 3 decimal places.)
