2. An article in Fortune (September 21, 1992) claimed that nearly one-half of all engineers continue academic studies beyond the B.S. degree, ultimately receiving either an M.S. or a Ph.D. degree. Data from an article in Engineering Horizons (Spring 1990) indicated that 117 of 484 new engineering graduates were planning graduate study. 2.1. Are the data from Engineering Horizons consistent with the claim reported by Fortune? Use a=0.05 in reaching your conclusions. Find the P-value for this test. 2.2. Discuss how you could have answered the question by constructing a two-sided confidence interval on p. Find the confidence interval.
