Question

Find the class midpoint of the FICO score interval 550-599.
FICO Score:400-449, 450-499, 500-549, 550-599, 600-649, 650-699, 700-749
Frequency:1, 5, 8, 19, 27, 10, 1
1)550
2)575
3)570
4)574.5

Answer 1

To find the class midpoint of the FICO score interval 550-599, you can use the following formula for the midpoint:

\[
\text{Midpoint} = \frac{\text{Lower Limit} + \text{Upper Limit}}{2}
\]

For the interval 550-599:

- Lower Limit = 550
- Upper Limit = 599

Now plug in the values:

\[
\text{Midpoint} = \frac{550 + 599}{2} = \frac{1149}{2} = 574.5
\]

Therefore, the class midpoint of the FICO score interval 550-599 is **574.5**.

The correct answer is:

4) 574.5
