Explanation / Answer

1)Arithmetic Mean=448/16=28.

2)The first quartile is the value for which 25% of the values in data set are smaller than it.

Here, First Quartile=21.

The second quartile or median is the value for which 50% of the values in data set lies below it.

Here, Median=27.

The third quartile is the value for which 75% of the values in data set lies below it.

Here, Q3=35.5.

Standard Deviation of this sample=7.124(approx).

Measure of Skewness=3*{(28-27)/7.124}=0.421111735.

2)0.421111735.

3)First Quartile=21.

4)Third Quartile=35.5

5)Interquartile Range=(35.5-21)/2=7.25.

6)Five number summary:

Minimum:19

First Quartile:21

Median:27

Third Quartile:35.5

Maximum:41.
