In 2013, 81.8% of first-year college students responding to a national survey said that they used the Internet frequently for research or homework. Administrators at a large state university believe that their current first-year students use the Internet more frequently than students in 2013 did. They find that 168 of an SRS of 200 of the university's first-year students said that they used the Internet frequently for research or homework. Is the proportion of first-year students at this university who said that they used the Internet frequently for research or homework larger than the 2013 national value of 81.8%? (a) Explain in words what the parameter p is in this setting. d. (b) What are the null and alternative hypotheses Ho and Ha? (c) What is the numerical value of the sample proportion p ? The P- value is the probability of what event? (d) The P-value is P = 0.210. Explain carefully why this evidence should lead administrators to fail to reject Ho.
