A survey of 366 Cook County residents is conducted, in which 253 of the respondents had shopped online inthe last three months.What proportion of the respondents had shopped online?Give the proportion as a fraction.Give the proportion as a percent, rounded to the nearest tenth of a percent.%In this problem, all of the conditions are met to construct a confidence interval using the methodimplemented on our calculator.Use your calculator to construct a 95% confidence interval for the proportion of all Cook County residentswho had shopped online in the three months before the study.%,In words, in the context of this problem, explain what this confidence interval means. (Note: This part willbe hand-graded. The computer will automatically mark it "wrong," but you will receive credit for a correctanswer when the test is hand-graded after the due date.)

Given: n = 366 X = 253 Formula Used: Confidence Interval = p^ ± Z*p^(1-p^)n
