A small company involved in e-commerce is interested in statistics concerning the use of e-mail. A poll found that 38% of a random sample of 1183 adults, who use a computer at their home, work, or school, said they do not send or receive e-mail. Complete parts a through e. a) Find the margin of error for this poll if we want 99% confidence in our estimate of the percent of American adults who do not use e-mail. ME= (Round to three decimal places as needed.) b) Explain what that margin of error means. O A. The margin of error (as a percent) is the value that should be subtracted from the 99% confidence level to obtain the pollsters' true confidence level. O B. The pollsters are 99% confident that the margin of error contains the true proportion of adults who do not use e-mail. O C. The margin of error is the width of the confidence interval that contains the true proportion of adults who do not use e-mail. O D. The pollsters are 99% confident that the true proportion of adults who do not use e-mail is within the margin of error (as a percent) of the estimated 38%. c) If we want to be 95% confident, will the margin of error be larger or smaller? O A. A 95% confidence interval leads to a larger margin of error. In order to Increase confidence, the interval must be wider. O B. A 95% confidence interval leads to a smaller margin of error. In order to decrease confidence, the interval must be narrower. O C. A 95% confidence interval leads to a smaller margin of error. In order to decrease confidence, the interval must be wider. O D. A 95% confidence interval leads to a larger margin of error. In order to increase confidence, the interval must be narrower. d) Find that margin of error. ME = (Round to three decimal places as needed.) e) In general, if all other aspects of the situation remain the same, will smaller margins of error involve greater or less confidence in the interval? O Smaller margins of error will be the result of less confident intervals. O Smaller margins of error will be the result of more confident Intervals
