Question

Twenty-two people were asked to rate a competitive beer on a taste scale of 0 to 100. Another 22 people were asked to rate our beer on the same taste scale. The file P09_63.xlsx contains the results. Do these data provide sufficient evidence to conclude, at the 1% significance level, that people believe our beer tastes better than the competitor’s? Assume ratings are at least approximately normally distributed.
