A research center survey of 2,380 adults found that 1,945 had bought something online. Of these online shoppers, 1,209 are weekly online shoppers. Complete parts (a) through (c) below. BEKER a. Construct a 95% confidence interval estimate of the population proportion of adults who had bought something online. SIS (Round to four decimal places as needed.) b. Construct a 95% confidence interval estimate of the population proportion of online shoppers who are weekly online shoppers. SxS (Round to four decimal places as needed.) c. How would the director of e-commerce sales for a company use the results of (a) and (b)? OA. A greater proportion of adults have purchased something online, but those adults who are weekly online shoppers make larger purchases, so the director of e-commerce sales may want to focus on those adults who are weekly online shoppers. OB. Since a greater proportion of adults have purchased something online than are weekly online shoppers, the director of e-commerce sales may want to focus on those adults who have purchased something
