Provide an appropriate response. Express your answer as a simplified fraction unless otherwise noted 23) The overnight shipping business has skyrocketed in the last ten years. The single greatest predictor of company's success has been proven time and again to be customer service. A study was conducted to study the customer satisfaction levels for one overnight shipping business. In addition to the customer's satisfaction level the customers were asked how often they used overnight shipping. The results are shown below in the following table. A customer is chosen at random. Given that the customer uses the company less than two tims per month, what is the probability that they expressed high satisfaction with the company? Satisfaction level 140 25 Frequency of Use High Medium Low TOTAL 32 per month 250 400 5 200 100 700 10 2-5 per month 140 70 5 per month TOTAL 460 220 20

Explanation / Answer

probability that they expressed high satisfaction and company less than two per month) = 250/700
P(customer uses the company less than two per month) = 400/700
P(high satisfcation given that less than two per month) = P(expressed high satisfaction and company less than two per month)) / P(customer uses the company less than two per month)
= (250/700)/ (400/700) = 250/400 = 0.625
