In 2006, 75.9 percent of first-year college students responding to a national survey said that they used the Internet frequently for research or homework. A state university finds that 168 of an SRS of 200 of its first-year students said that they used the Internet frequently for research or homework. You wonder if the proportion of first-year students at this university who said that they used the Internet frequently for research or homework differs from the national value, 75.9 percent. Consider p as the proportion of first year college students at this university who use the Internet frequently for research or homework. The hypotheses that you will test are: H0: p = 0.759, Ha: p â 0.759
If the null hypothesis is true, the proportion who use the Internet frequently for research or homework from an SRS of 200 students would have (approximately) a Normal distribution with mean 0.759 and standard deviation . (Give your answer to four decimal places.)
