We are studying the times required to solve two elementary math problems. Suppose we ask four students to attempt Problem A and four other students to attempt Problem B. Assume everything is independent and normal. The results are presented below (in seconds) Problem A Problem B
20 35
30 20
15 50
40 40
Assuming that the variances are unequal, find a two-sided 95% confidence interval for the difference in the means between Problems A and B.
