Which of the choices is the variance of the sample shown here? 35,37,42,57,61,70

First, you need to find the mean of all this set of numbers. You would add them all together and then divide by 6 which is 50.5.

Now you find the sample variance. Subtract each number from the mean. 

15.5, 13.5, 8.5, -6.5, -10.5, -19.5 

After, you square each value and add them. 

240.25+182.25+72.25+42.25+110.25+380.2... 
= 1027.5 

Now divide by 5 (because it's a sample variance) and you get 205.5.

The answer to the question is d
