The mean of this distribution is 10, and the standard deviation is 3. The probability of completing the project in 7 or fewer days is the same as the probability of completing the project in 13 days or more. MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 6) 6) The following is an opportunity loss table.

A) Alternative 1 B) Alternative 2 C) Alternative 3 D) State of Nature A E) Does not matter B-2Explanation / Answer
Q1) Answer is B) positive correlation coefficient.
As the line is linear on positive x and y axes, and an increase in x is leading to an increase in y, the correlation coefficient is positive.
Q2) Given minimum days of 7 are just 3 days distant from the mean of 10 days and maximum days of 13 are just 3 days distant from the mean of 10 days. As the distance on left and right hand side of mean is equal, the probability of project completion is same.
Answer is True.
Q3) Answer is C) Alternative 3.
Minimizing the maximum regret.
