Question 3 Not yet answered Marked out of 3.00 Flag question For the given data set match the parameters with correct values. 42 33 31 34 19 28 38 43 14 28 median? Choose... mean? Choose... What percent of the data are less than 30? Choose...

Answer 1

The data is arranged in ascending order:

14,19,28,28,31,33,34,38,42,43

The middlemost values are 31 and 33

So the median is

$=\frac{31+33}{2}=\frac{64}{2}=32$

The median is 32

The mean is given by

$=\frac{14+19+28+28+31+33+34+38+42+43}{10}=\frac{310}{10}=31$

The mean is 31

4 out of 10 data points are less than 30. So the percentage of data which is less than 30 is

$=\frac{4*100}{10}=40$

So 40% of the data is less than 30
