Answer 1

Answer:

Class-interval.

Step-by-step explanation:

In the interval 50-60, the lower limit is 50 and the upper limit is 60. We know that the class-mark is the average of limits of class-interval. Hence, the class mark of the interval 50-60 is 55.

Answer 2

Answer:

Step-by-step explanation:

Lower limit is 50 whereas, the upper limit is 60

For calculating the mid value you will have to add both 50+60=110

Now, 110/2=55.

Now 55 is mid-value.
