The Overnight Shipping Business Has Skyrocketed in the Last Ten

question 207

Short Answer

The overnight shipping business has skyrocketed in the last ten years. The single greatest predictor of a company's success is customer service. A study was conducted to determine 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: $\begin{array}{c|ccc|c} &{\text { Satisfaction level }} & \\\text { Frequency of Use } & \text { High } & \text { Medium } & \text { Low } & \text { TOTAL } \\\hline<2 \text { per month } & 250 & 140 & 10 & 400 \\\text { 2-5 per month } & 140 & 55 & 5 & 200 \\>5 \text { per month } & 70 & 25 & 5 & 100 \\\hline \text { TOTAL } & 460 & 220 & 20 & 700\end{array}$

A customer is chosen at random. Given that the customer uses the company more than five times per month, what is the probability that the customer expressed medium satisfaction with the company?
A) $\frac { 1 } { 4 }$

B) $\frac { 5 } { 44 }$

C) $\frac { 1 } { 28 }$

D) $\frac { 59 } { 140 }$

• A) \(\frac { 1 } { 4 }\)
• B) \(\frac { 5 } { 44 }\)
• C) \(\frac { 1 } { 28 }\)
• D) \(\frac { 59 } { 140 }\)
