A Pew Internet Project Data Memo presented data comparing adult gamers with teengamers with respect to the devices on which they play. The data are from twosurveys. The adult survey had 1063 gamers, while the teen survey had 1064 gamers.The memo reports that 54% of adult gamers played on game consoles (Xbox,PlayStation, Wii, etc.), while 89% of teen gamers played on game consoles. Supposeyou want to construct a 95% confidence interval for the difference. What is theestimate and margin of error that you would use? The estimate of the difference isand the margin of error is(Please round totwo decimal places)

In a study, 110 children of a certain race in a certain city were randomly assigned to one of two groups: one group enrolled in a preschool, and the other group did not. A research question was whether attendance at preschool had an effect on high school graduation. The accompanying table shows whether the students graduated from regular high school or not and includes both boys and girls. Find a 95% confidence interval for the difference in proportions, and interpret it. Click the icon to view the data. Step 1: Calculate percentages Looking at children who went to preschool, 30 or 55.6%, graduated from high school. Looking at the children who did not go to preschool, what percent graduated from high school? 54' 30.4 % of children who did not go to preschool graduated from high school. (Round to one decimal place as needed.) Step 2: Compare In this sample, the children who attend preschool are more likely to graduate than the children who don't attend preschool. Step 3: Verify…
In a study investigating the difference in food preferences between men and women, researchers asked subjects to indicate whether they liked or disliked certain foods. One question was about liking cabbage. Twenty percent of a sample of 75 men liked cabbage, while 41% of a sample of 100 women indicated that they liked cabbage. Provide two confidence intervals, one for the proportion of men who like cabbage and one for the proportion of women who like cabbage. Use a 95% confidence level. State whether or not the populations are different and explain how you know this.

You need to use Stata to look up the dataset and its variables. Use Stata Companion Textbook. (Dataset: NES. Variables: spend8, [pw=nesw].) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the mean and lincom commands. You then will draw inferences about the population mean. (Remember to specify nesw as the probability weight.) The spend8 variable has a sample mean of ______. Make sure you use [pw=nesw] so your results are nationally representative. There is a probability of .95 that spend8’s true population mean falls between a score of ______ at the low end and a score of ______ at the high end. A student researcher…
A university planner wants to determine the proportion of undergraduate students who plan to attend graduate school. She surveys 54 current students and finds that 27 would like to continue their education in graduate school. Which of the following is the correct 90% confidence interval estimate for the proportion of undergraduates who plan to attend graduate school?
A 95% confidence interval is constructed in order to estimate the proportion of adults who own an iPhone. The resulting interval has a margin of error of 0.043. Which of the following would be the margin of error for a 90% confidence interval based on the same sample of data?
A Pew Internet Project Data Memo presented data comparing adult gamers with teen gamers with respect to the devices on which they play. The data are from two surveys. The adult survey had 1063 gamers, while the teen survey had 1064 gamers. The memo reports that 54% of adult gamers played on game consoles (Xbox, PlayStation, Wii, etc.), while 89% of teen gamers played on game consoles. Suppose you want to construct a 95% confidence interval for the difference. You want to test were or not the two proportions (adult using consoles vs teens using consoles) are the same. You have to calculate a pooled estimate for the proportion. What would that be? (Please round to three decimal places)
You may need to use the appropriate technology to answer this question. Periodically, customers of a financial services company are asked to evaluate the company's financial consultants and services. Higher ratings on the client satisfaction survey indicate better service, with 7 the maximum service rating. Independent samples of service ratings for two financial consultants are summarized here. Consultant A has 10 years of experience, whereas consultant B has 1 year of experience. Use ? = 0.05 and test to see whether the consultant with more experience has the higher population mean service rating. Consultant A Consultant B n1 = 16 n2 = 10 x1 = 6.83 x2 = 6.25 s1 = 0.66 s2 = 0.75 (a) State the null and alternative hypotheses.
