Our friend the waffleman wishes to estimate the average revenue from ticket sales at Broadway for the past year. Using a random sample of 120 plays from the past year, she computed a 87% confidence interval of [114, 122]. She used a histogram to verify that her data was normally distributed. Which of the following is a correct statement? Select one or more: O a. If our friend the waffleman were to repeatedly take random samples of 120 plays and construct 87% confidence intervals with each sample, approximately 95% of the confidence intervals would contain the true average revenue from ticket sales at Broadway from the past year. O b. With the information given in this problem, we cannot calculate the margin of error. O c. If our friend the waffleman selects a new sample of 140 plays and creates a new 87% confidence interval, the new interval would be wider than the interval calculated on 120 plays. d. We are 87% confident that the average revenue from ticket sales of the sample will be between 114 and 122. e. We are 87% confident that the true average revenue from ticket sales at Broadway from the past year is in the

A sample of 100 shoppers chosen at random from all shoppers in a given province indicated that 55% of them preferred a particular store (Shoprite).i. Find a 95% confidence interval for the proportion of all the shoppers that preferred Shoprite.ii. How large a sample of shoppers should we take in order to be 95% confident that the shoppers will buy from Shoprite?
You are interested in constructing a 90% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 427 randomly selected caterpillars observed, 45 lived to become butterflies. a. Use 3 decimal places to complete the following statement: With 90% confidence the proportion of all caterpillars that lived to become a butterfly is between and . b. If many groups of 427 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about percent will not contain the true population proportion.
The dean of students at a large college is interested in learning about their opinions regarding the percentage of first-year students who should be given parking privileges in the main lot. 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). Which of the following may have an impact on the confidence interval, but is not accounted for by the margin of error? response bias O nonresponse bias O sampling variation O undercoverage bias
Suppose a 95% confidence interval for the difference in test scores between Class 1 and Class 2 (in that order) is the following: 9 +/− 2. These results were based on independent samples of size 100 from each class. Now suppose you switch the order of Class 1 and Class 2 in your analysis but keep the data labeled correctly in terms of which class they came from. Which of the following statements is false? A) You can't do it this way. You'll get negative numbers for the difference in the means and/or negative numbers for the standard error. B) You are confident that the average for Class 2 is 7 to 11 points lower than for Class 1. C) You are still confident that the classes have significantly different mean scores. D) Your 95% confidence interval will now be entirely negative: from −7 to −11.

A survey is taken of 250 students, and a P of 0.45 is found. The same survey is repeated with 1,000 students, and the same value is found. Compare the two 95% confidence intervals. What is the relationship? Is the margin of error for the second one four times smaller? How much smaller is it?

you conducted additional studies with these men and found the following: a. The RR for those who drank one drink per day was 1.50 (95% CI:1.32-1.67) in comparison to the abstainers. b. For those men who drank three or more drinks per day the RR compared to the abstainers was 4.20 (95% CI 2.68-5.85). Question: We can tell from the Confidence Intervals provided in #7 whether there are likely more people in the “one drink a day” group or the “3+ drinks per day” group. Which one likely has more people and how can we tell?
