question 119

Short Answer

SCENARIO 19-6
A student wanted to find out the optimal strategy to study for a Business Statistics exam. He
constructed the following payoff table based on the mean amount of time he needed to study every
week for the course and the degree of difficulty of the exam. From the information that he gathered
from students who had taken the course, he concluded that there was a 40% probability that the exam
would be easy. $$\begin{array} { | l | l | l | l | } \hline & 16 \text { hours } & 8 \text { hours } & 4 \text { hours } \\\hline \text { Easy Exam } & 40 & 60 & 80 \\\hline \text { Difficult Exam } & 100 & 50 & 0 \\\hline\end{array}$$
-Referring to Scenario 19-6, what is the coefficient of variation of spending 8 hours per week on
average studying for the exam?
