Question

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. Are the data from Engineering Horizons consistent with the claim reported by Fortune? Use a = 0.10 in reaching your conclusions. Find the P-value. Give your answer. The true proportion of engineering students planning graduate studies significantly different from 0.5 at a = 0.10. The P-value is less than (choose the least possible).

Answer 1

Since the p–value is less than the significance level, the null hypothesis is rejected. The true proportion of engineering students planning graduate studies significantly different from 0.5 at α=0.10
