D Question 8 1 pts Researchers conducted a cola-tasting experiment. Five hundred randomly selected people were each given a half-cup of Brand A and a half-cup of Brand B. All 500 people tasted both colas and then rated the taste of each cola. The rating scale was from O (the taste is horrible) to 10 (the taste is great). For each person, a coin was tossed to decide whether the person would taste Brand A first or Brand B first. The confidence interval for the difference in population mean ratings between Brand A and Brand B is below: data: Brand A and Brand B 95 percent confidence interval: (- 0.48, 0.05) Using the confidence interval, what can you conclude about the difference of ratings in the taste between Brand A and Brand B? The sample provides evidence to conclude that there is a difference in population mean ratings. The sample does not provide evidence to conclude that there is a difference in population mean ratings. It is reasonable to conclude that the difference in sample means is positive. O It is reasonable to conclude that the difference in population means is negative
