Achieving a high score on the LSAT examination is a prerequisite for getting accepted to law school. A random sample of 15 students from Law School 1 had an average LSAT score of 680 with a standard deviation of 84. A random sample of 12 students from Law School 2 had an average LSAT score of 634 with a standard deviation of 92. Making appropriate assumptions, find a 90% confidence interval for the difference between mean LSAT scores at these two schools.
