Question

A frequency distribution was created and a portion of the data was lost. You are given that the lower class limit is 20 and the midpoint is 30. What is the upper class limit?

Answer 1

To find the upper class limit, calculate the class width by subtracting the lower class limit from the sum of the midpoint and upper class limit. Then use the formula Upper Class Limit = Midpoint + (Class Width / 2). In this case, the upper class limit is 50.

Step-by-step explanation:

To find the upper class limit, we need to calculate the class width. The class width is the difference between the lower class limit and the upper class limit. Since the midpoint is given as 30 and the lower class limit is 20, we can use the formula: Upper Class Limit = Midpoint + (Class Width / 2).

Let's calculate the class width. The midpoint is 30, so the lower class limit + upper class limit is equal to 2 * 30, which gives us a sum of 60. Since the lower class limit is 20, we can subtract that from the sum to get the class width: 60 - 20 = 40. Now we can find the upper class limit using the formula: Upper Class Limit = 30 + (40 / 2) = 50.
