Beyond the Answer

To find Quartile 1 (Q1), we first need to arrange the given camera prices in ascending order: .
Next, since there are 14 data points, we can find Q1 by locating the value at the 25th percentile position. This can be calculated using the formula , where is the number of observations.
Substituting , we get . This means Q1 is located between the 3rd and 4th data points. Since the 3rd data point is and the 4th is , we can calculate:
Thus, Quartile 1 (Q1) is .
However, since this doesn’t match any of the listed options, the closest answer is “none of these.”

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^.
