Following are the lengths in yards of the nine holes of the University Golf Course: 480,460,450,380,360,350,330,180,160 Find each of the following measures with respect to the lengths of the holes:
d. Standard deviation
36.07263

The mean is 350.0
The square of the mean is 122,500
The mean of the squares is 134,211
The difference of the last 2 numbers is 11,711. That equals the square of the standard deviation.
The standard deviation is much larger than 36.07
