Their new design was seen by 756 first- time visitors over a month, and of those, 66 registered. (a) To check the conditions required to construct a confidence interval, we'll note that the visitors were independent, and have you verify that np and n(1 - p) are both at least 10: np 66 and n(1 - p) = 690 (b) Compute the standard error to three decimal places: SE = 0.01 (c) Construct a 90% confidence interval for the faction of first-time visitors of the site who would register under the new design (assuming stable behaviors by, new visitors over time). [Recall: the formula for the endpoints of a confidence interval of proportions is p 1 z . SE. Use the z-score to 3 decimals as presented in class for the 90% confidence interval.] 10.4 x ) Submit
