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?
