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 $51$. Hence 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 an empty cell, write: =VAR(A1:A10). Doing this, we find that the variance is $245.1$.
e) The range is:
$79−34=45$
