Answer 2

The mean number of vehicles owned by the families in Class B is:

2

Explanation:

We know that the mean id calculated as the average of the data entries.

Now for class B we make a frequency table as follows:

Number of vehicles(x) Number of families(y) xy

0 3 0

1 4 4

2 10 20

3 7 21

5 1 5

Total number of families= 3+4+10+7+1= 25

∑ xy= 0+4+20+21+5= 50

Hence, the Mean is:

`Mean=(\sum xy)/(Number\ of\ families)\\\\i.e.\\\\Mean=(50)/(25)\\\\i.e.\\\\Mean=2`
