Beyond the Answer

To calculate the -score for the oldest senator who is 82 years old, you use the formula:
Where:
  • = age of the senator (82)
  • = mean age (63)
  • = standard deviation (12)
Plugging in the values:
So the -score for the oldest senator is approximately .
For the youngest senator, who is 36 years old, you would apply the same formula:
This means the -score corresponding to the youngest senator is approximately .

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.
