Answer 2

Final answer:  9.5 - 19.5,  19.5 - 29.5,  29.5 - 39.5,  39.5 - 49.5

Given that: We are given inclusive class intervals 10 - 19, 20, 29, 30 – 39, 40 – 49.

To find: We have to find exclusive class intervals corresponding to the

inclusive class intervals 10 - 19, 20, 29, 30 – 39, 40 – 49.

Explanation:

• There are two steps to convert inclusive class interval to exclusive class interval.

Step 1: Find out the difference between upper limit of the class interval and lower limit of the next class interval. Then calculate half of the difference.

Step 2: Add that value to upper limit of the each class interval and subtract that value from the lower limit of each class interval.

• Here the class intervals are 10-19, 20-29, 30-39 and 40-49 uniform.

• The difference between upper limit of the class interval and lower limit of the next class interval is

                =(20 – 19) = (30 – 29) = (40 – 49) = 1

• Half of the difference = 1/2 = 0.5

• To find exclusive class interval, add 0.5 to upper limit of the each class interval and subtract 0.5 from the lower limit of each class interval.

• 10 - 19 corresponding exclusive class interval, (10 - 0.5) - (19 + 0.5) = 9.5 – 19.5

• 20-29 corresponding exclusive class interval, (20 - 0.5) - (29 + 0.5) = 19.5 – 29.5

• 30 - 39 corresponding exclusive class interval,

       (30 - 0.5) - (39 + 0.5) = 29.5 – 39.5

• 40 - 49 corresponding exclusive class interval,

       (40 - 0.5) - (49 + 0.5) = 39.5 – 49.5

• Exclusive class interval corresponding to the inclusive class intervals 10 - 19, 20, 29, 30 – 39, 40 – 49  are

       9.5 - 19.5,  19.5 - 29.5,  29.5 - 39.5,  39.5 - 49.5
