6. In a recent survey, office workers were asked how long they normally took to respond to e-mail. Thirty-six percent said "as soon as I return to my desk", 35% said "within an hour or two," 24% said "before the end of the business day", and 5% said "when I can". Assume that these results hold true for the population of all office workers in 2020. Suppose we denote these responses by A, B, C, and D, respectively. A recent random sample of 400 office workers were asked the same question and it yielded the frequency distribution shown in the following table: Respnose A B C D Frequency 125 140 115 20 At 1% level of significance, can you conclude that the current distribution of responses differ from the 2020 distribution
