Question

Lisa and complains a lot about her drink being flat infact local restaurant manager can consider banning her for making spurious complaints but then if he wondered if you should put forward for quality control job with the fizzy drinks company . if Lisa says a drink is flat how likely is she to be correct how good is he sad setting whether or not a drink is flat would Lisa be good at the quality controlled job justify your answer​

Answer 1

A) The probability of Lisa being correct if she says a drink is flat is; 83.3%

B) The level of Lisa's accuracy in detecting a drink that is flat is; 83.3%

C) The reason why Lisa should be considered for to job is because; she has a high accuracy level and is not just complaining unnecessarily.

How do you interpret the right probability?

From the table showing Lisa's response to the last 100 drinks she bought attached, we see that;

A) When the drink was flat, she complained 5 times out of 6. Thus, if the drink is flat, the probability of her complaint being correct = 5/6 = 83.3%

B) 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.

C) 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.
