Use the sample data and confidence level given below to complete parts (a) through (d). in a study of cell phone use and brain hemispheric dominance, an internet survey was e-mailed to 2346 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. click the icon to view a table of z scores. a) find the best point estimate of the population proportion p. 0.507 (round to three decimal places as needed.) b) identify the value of the margin of error e. eequals 0.020 (round to three decimal places as needed.) c) construct the confidence interval. 0.487less than p less than 0.527 (round to three decimal places as needed.) d) write a statement that correctly interprets the confidence interval. choose the correct answer below. a. one has 95% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. b. 95% of sample proportions will fall between the lower bound and the upper bound. c. there is a 95% chance that the true value of the population proportion will fall between the lower bound and the upper bound. d. one has 95% confidence that the sample proportion is equal to the population proportion.

Acheese processing company wants to estimate the mean cholesterol content of all one-ounce servings of a type of cheese. the estimate must be within 0.67 milligram of the population mean. (a) determine the minimum sample size required to construct a 95% confidence interval for the population mean. assume the population standard deviation is 3.18 milligrams. (b) the sample mean is 25 milligrams. using the minimum sample size with a 95% level of confidence, does it seem likely that the population mean could be within 3% of the sample mean? within 0.3% of the sample mean? explain.
