SOLUTION

TO DETERMINE

The upper limit of the class interval 40 - 50

CONCEPT TO BE IMPLEMENTED

Class Interval :

When the number of sample values are large in number and are in wide range, then the whole data is divided in a number of several groups according to the size of the sample. Each of these groups, made as above, is known as class interval

Upper limit :

In the frequency table if both ends of any class interval are specified then these end values are known as class limits. The lower end value is called lower class limit whereas the upper end value is called upper class limit

EVALUATION

Here the given class interval 40 - 50

Now

The lower end value = 40

The upper end value = 50

Hence the required upper limit of the class interval 40 - 50 is 50
