Ernesto is a web developer who is looking to determine which of two types of advertisements are the most cost effective. He suspectsthat advertisements with animations generatemore clicks than advertisements without animationsbut wantsto confirm his intuitionbefore he starts recommending advertisements with animations to his clients. Ernesto createsadvertisements with animations for12

different products and then createsadvertisements without animations for those same products. Then he measures the click-through rate for those advertisements. The data areprovidedbelow (given as percentages of total visitors to the site who clicked on the advertisement). Assume that the conditions required for this hypothesis test are satisfied.

Use a calculator to test the paired data, where?=0.01

. Compute the sample differencesd

usingd=Without?With

. Which of the following statements are accurate for this hypothesis test in order to evaluate the claim that the true mean difference between theclick rates of advertisementswithout animations and the click rates of advertisements with animations isless than0

Fail to reject the null hypothesis that the true mean difference between the click rates of advertisements without animations and the click rates of advertisements with animations is equal to 0. Based on the results of the hypothesis test, there is enough evidence at the a = 0.01 level of significance to suggest that the true mean difference between the click rates of advertisements without animations and the click rates of advertisements with animations is less than 0. Based on the results of the hypothesis test, there is not enough evidence at the a = 0.01 level of significance to suggest that the true mean difference between the click rates of advertisements without animations and the click rates of advertisements with animations is less than 0.
