The October 2011 ISACA Shopping on the Job Survey asked employees, “During the holiday season (November and December), how much total time do you think an average employee at your enterprise spends shopping online using a work-supplied computer or smartphone?” Among those who responded, 3% said 0 hours, 24% said 1 to 2 hours, 22% said 3 to 5 hours, and 51% said 6 or more hours (www.isaca.org/SiteCollectionDocuments/2011-ISACA-Shopping-on-the-Job-Survey-US.pdf). Suppose that another poll conducted recently asked the same question of 215 randomly selected business executives, which produced the frequencies listed in the following table.
Test at a 2.5% significance level whether the distribution of responses for the executive survey differs from that of October 2011 survey of employees.
