Answer
a. 53.3
b. 52.0
c. 15.7
d. 245.1
e. 45
Work Step by Step
a. The mean is:
$\frac{51+63+36+43+34+62+73+39+53+79}{10}=53.3$
b. The median is the middle term, which in this case can either be 53 or 51. Thus, we take the average of these to get that the median is 52.0.
c. Using a standard deviation calculator, we find that the standard deviation is 15.7.
d. To solve this problem, put the data in Microsoft Excel in cells A1 through A10. Then, in a empty cell, write $=VAR(A1:A10)$. Doing this, we find that the variance is 245.1.
e. The range is:
$=79-343=45$
