I WILL GIVE 5 REWARD POINTS TO THOSE WHO ANSWERED THIS SIMPLE TASK

1.AlacrityBrokerage, Inc. conducted a survey of a sample of 500 customers to determine if the service it provides to affluent clients is the same as the service it provides to lower-income clients. The brokerage classified its clients into three socioeconomic classes: AB, Upper and Middle C, and lower C and below. The sample respondents were asked to rate the service as Outstanding, Average, or Poor. The survey results (partial):

107 respondents belonged to the AB class.

217 respondents belonged to the Upper and Middle C class.

153 respondents said the service was Outstanding.

41 AB respondents said the service was Outstanding.

64 Upper and Middle C respondents said the service was Outstanding.

16 AB respondents said the service was Poor.

33 Upper and Middle C respondents said the service was Poor.

If the respondent belonged to the Upper or Middle C class, the probability of reporting Average service was 0.10416. If the respondent belonged to the Lower C class, the probability of reporting Average service was 0.068992.
