Researchers wanted to see if a certain image in ads affected people's ability to remember the item being advertised. They found two ads for each of 10 similar items, one with the image and one without. Then they showed the ads in random order to 39 randomly selected people for one minute and asked them to list as many of the items as they could, with the accompanying results for the number of items remembered. Is there evidence that the image mattered? Use α=0.05 what is the test statistic? use no image - image as the difference. what is the p value?
