State legislators propose cutting funding to public universities. College administrators oppose this, claiming that across the state, freshmen enrollment has increased dramatically over the last decade. To substantiate their claim, they randomly sample 10 institutions. The administrators find that the average freshmen enrollment 10 years ago was 934.1 with a standard deviation of 120.52 (sample 1). They independently sample another IO institutions and find that the average freshmen enrollment is currently 1302.2 witn a standard deviation of 178.6 (sample 2). Assuming both populations are normal and have equal variance, construct a 98% confidence interval on tne mean difference in freshmen enrollment at state public institutions over the last decade.
