1. The probability of Lisa being correct if she says a drink is flat is; 83.3%
2. The level of Lisa's accuracy in detecting a drink that is flat is; 83.3%
3. The reason why Lisa should be considered for to job is because; she has a high accuracy level and is not just complaining unnecessarily.
Step-by-step explanation to each question (numbered): As shown in the chart…
1) We know this from the chart that shows when the drink was flat, she complained 5 times out of 6. If the drink is flat, the chances of her complaining being correct = 5/6 = 83.3%
2) Since she is 83.3% correct in detecting whether a drink is flat, then we can say that Lisa is 83.3% very good at detecting whether a drink is flat.
3) It would be good in recommending Lisa for the quality control job because she only complained 3 times out of 94 times that the drink was not flat while she was correct 5 out of 6 times when the drink was flat. Thus, she has a high accuracy level and is not just complaining unnecessarily.
