Use the sample data and confidence level In a study of cell phone use and brain hemispheric dominance, an Internet survey was e-mailed to 2628 subjects randomly selected from an online group involved with ears. 1189 surveys were returned. Construct a 95% confidence interval for the proportion of returned surveys. a) Find the best point estimate of the population proportion p. (Round to three decimal places as needed.) b) Identify the value of the margin of error E. (Round to three decimal places as needed.) c) Construct the confidence interval. (Round to three decimal places as needed.)

Refer to the data set of 20 randomly selected presidents given below. Treat the data as a sample and find the proportion of presidents who were taller than their opponents. Use that result to construct a 95% confidence interval estimate of the population percentage. Based on the result, does it appear that greater height is an advantage for presidential candidates? Why or why not? Refer to attchment ** QUESTION** Construct a 95% confidence interval estimate of the percentage of presidents who were taller than their opponents. ? % <p< ? %

in a study of government financial aid for college students it becomes necessary to estimate the percentage of full-time college student who earn a bachelors degree in four years or less find the sample size need to estimate that percentage use a 0.02 margin of error and use a confidence level of 90%. assume that nothing is known about the percentage being estimated n = ? assume prior studies have shown that about 45% of full-time college students earn a bachelors degree in four years or less n=? does the ad a knowledge in part B have much affect on the sample size? a) yes using the additional survey information from part B only slightly increase the sample size b) no using the additional survey information from part b does not change the sample size c) yes using the additional Survey information from part be dramatically reduces the sample size d) no using the additional survey information from part B only slightly reduces the sample size
