Zinser Industries has a similar product that is sold under two different brand names and wants to know if the quality is perceived differently between the two brand names. In a survey of current customers of each brand, they ask respondents to rate the brand on a 1 to 10 scale where 1 is very low quality and 10 is very high quality. For the 175 customers of Brand A surveyed, the average rating was 7.2 with a standard deviation of 1.5. For the 150 customers of Brand B surveyed, the average rating was 7.9 with a standard deviation of 2.0. Using a 95% confidence level, are these brands viewed as different quality?
