In testing a certain kind of missile, target accuracy is measured by the average distance X (from the target) at which the missile explodes. The distance X is measured in miles and the sampling distribution of X is given by: Calculate the variance of this sampling distribution. X ||0 ||10||50|100|| 1/3/ P(X)/28/1474

Expert Solution
Step 1

Solution-:

We have given sampling distribution of X:

X 0 10 50 100
P(X) 1/28 1/14 1/7 3/4

We want to find the variance of this sampling distribution?
