A research company polled a random sample of 500 teens about Internet use. 37% of those teens reported going online several times a day-a fact of great interest to advertisers. Complete parts a through c below. a) Explain the meaning of $\hat{p}$ = 0.37 in the context of this situation. A. The meaning of $\hat{p}$ = 0.37 is that the researchers have 95% confidence that 37% of the 500 teens in the sample said they go online several times a day. B. The meaning of $\hat{p}$ = 0.37 is that 37% of the 500 teens in the sample said they go online several times a day. This is the researchers' best estimate of p, the proportion of the 500 teens in the sample who said they do so. C. The meaning of $\hat{p}$ = 0.37 is that 37% of the 500 teens in the sample said they go online several times a day. This is the researchers' best estimate of p, the proportion of all U.S. teens who would say they do so. D. The meaning of $\hat{p}$ = 0.37 is that the researchers have 95% confidence that 37% of all U.S. teens would say that they go online several times a day. b) Calculate the standard error of $\hat{p}$. SE ($\hat{p}$)= (Round to three decimal places as needed.)
