Question 22 (1 point) In order to estimate the proportion of individuals who read at least one book per month, a random sample of individuals at a book fair was selected, and they were asked whether or not they read at least one book per month. Their responses are shown below. Responses Frequency Yes, I read at least one book per month 640 No, I do not read at least one book per month 160 Assume alpha = .05. What is the confidence interval for this proportion? (These are rounded.) .772 to .828 1.3 to 1.5 O .738 to .862 .70 to .90 Question 23 (0.5 points) In order to estimate the proportion of individuals who read at least one book per month, a random sample of individuals at a book fair was selected, and they were asked whether or not they read at least one book per month. Their responses are shown below.Question 21 (0.5 points) In order to estimate the proportion of individuals who read at least one book per month, a random sample of individuals at a book fair was selected, and they were asked whether or not they read at least one book per month. Their responses are shown below. Responses Frequency Yes, I read at least one book per month 640 No, I do not read at least one book per month 160 Assume alpha = .05. Which is the correct way to calculate margin of error for this problem? O tan Vp(1 - p) O Zal Vp(1 - p) O za VP(1 - p)in Question 22 (1 point) In order to estimate the proportion of individuals who read at least one book per month, a random sample of individuals at a book fair was selected, and they were asked whether or not they read at least one book per month. Their responses are70 to .90 Question 23 (0.5 points) In order to estimate the proportion of individuals who read at least one book per month, a random sample of individuals at a book fair was selected, and they were asked whether or not they read at least one book per month. Their responses are shown below. Responses Frequency Yes, I read at least one book per month 640 No, I do not read at least one book per month 160 Assume alpha - .05. Librarians believe that these numbers have been declining. Currently, they argue that number of people who read 1 book each month or less is under 75%. What do you tell the librarians based on your results? Nobody reads anymore. Everyone watches stories on some kind of video device. 75% would be outside the confidence limits based on this data. We don't have enough information to respond to this idea. (75% would fall within the confidence limits based on this data.The questions in the proportion section all use the same data. It can be useful to write down you answers.
