Answer 2

Given:

The mid-points of the class interval are 10, 15, 20, 25, 30

To find:

The last class interval of the distribution

Solution:

We can find the interval by following the given process-

We know that we can find the interval by calculating the class limit and size.

To calculate the class interval, we will have to make the difference of consecutive midpoints.

Class interval=15-10=5

Now we can calculate the class limits for the given midpoints by using the following-

Lower limits= Midpoint - class interval/2

Upper limit=Midpoint + class interval/2

For the last class interval, the midpoint is 30.

The lower limit=30-5/2

=30-2.5

=27.5

The upper limit= 30+5/2

=30+2.5

=32.5

The class interval= 27.5 to 32.5.

Therefore, the last class interval of the distribution is 27.5-32.5.
