Pew Research in 2018 polled a random sample of 1058 U.S. teens (ages 13-17) about Internet use. 44.7% reported that they were online "almost constantly" -a fact of great interest to advertisers. Complete parts a through c below. a) Explain the meaning of p^=0.447 in the context of this situation. Choose the correct answer below. A. The meaning of p^=0.447 is that 44.7% of the 1058 teens in the sample reported that they were online "almost constantly." This is the researchers' best estimate of p, the proportion of all U.S. teens who would say that. B. The meaning of p^=0.447 is that 44.7% of the 1058 teens in the sample reported that they were online "almost constantly." This is the researchers' best estimate of p^, the proportion of the 1058 teens in the sample who said that. C. The meaning of p^=0.447 is that the researchers have 95% confidence that 44.7% of all U.S. teens would report that they were online "almost constantly." D. The meaning of p^=0.447 is that the researchers have 95% confidence that 44.7% of the 1058 teens in the sample reported that they were online "almost constantly." b) Calculate the standard error of p^. SE(p^)= ◻ (Round to five decimal places as needed.)
