If The Lower Boundary Is 29.5 And The Interval Width Is 5, What Is The Upper Boundary?

If the lower boundary is 29.5 and the interval width is 5, what is the upper boundary?

 

Answer:

34.5

Step-by-step explanation:

We can get the lower class boundary by subtracting .5 to the lower class limit while adding .5 to the upper class boundary to get the upper class limit.

Since the lower boundary is already given which is 29.5, we have to get the value of the lower class limit first by adding .5 to 29.5

29.5 + .5 = 30

The lower class limit is 30.

The interval width is 5 so starting from 30, we should count up to 5 numbers - 30, 31, 32, 33, 34.

Since the upper class limit has been distinguished, add .5 to it to get the upper class boundary.

34 + .5 = 34.5
