Ans. Follow these steps to construct a histogram if only mid-values of class interval are given:

Subtract the first mid-value from the second mid-value, let the difference is h
divide the difference h by 2 = h/2
Subtract h/2 from first mid-value to get lower limit of first class-interval and add h/2 in first mid-value to get upper limit of class interval.
repeat all the above stated steps for all remaining mid-values to get all class interval.
Now you get all class interval.
draw the histogram using these class interval
