Transcribed Image Text:The Kaiser Family Foundation comissioned an extensive survey in 2004 that investigated the degree to which American youth from ages 8 - 18 have access to various forms of media. They
distributed written questionnaires to a random sample of 2032 youths in this age range. Among the 2032 youths who were sampled, 49 % reported having a video game player and
31 % reported having a computer in their bedroom.
Round your answers to three decimal places, if required.
a. Determine a
90 %
confidence interval for the population proportion of American youths who have a video game player in their bedrooms.
b. Repeat part a for the proportion who have a computer in their bedrooms.
c. Determine the margin-of-error (half-width) for each of these confidence intervals.
The margin-of-error for the 90 % CI for the population proportion of American youths who have a video game player in their bedroom is
The margin-of-error for the 90 %0 CI for the population proportion of American youths who have a computer in their bedroom is

He sends out an email survey to all students about this issue. A large number of first-year students reply but very few sophomores, juniors, and seniors reply. Based on the responses he receives, he constructs a 90% confidence interval for the true proportion of students who believe first-year students should be given parking privileges in the main lot to be (0.71, 0.79).

They each obtain a random sample of coffee drinkers, and, in each sample, the proportion who drink more than one cup of coffee per day is 0.40. Ellie and Alec each use their sample data to construct a confidence interval. Ellie’s interval is from 0.286 to 0.514, and Alec’s interval is from 0.346 to 0.474. One of these intervals was computed correctly, but the other was not. Which interval must be incorrect? A. Ellie’s interval must be incorrect. B. Alec’s interval must be incorrect. C.
