The advertising agency states the average increase in website traffic after a social media campaign is greater than 20 percent. If we would like to test the advertising agency's claim with a hypothesis test using a significance level of α = 0.015, what is the rejection region? Use the graph below to show the rejection region. First, move the blue dot to choose the appropriate test (left-, right, or two- tailed). Then, slide the shaded region(s) to represent the rejection region.
