Question Find the midpoint of the class interval 95-99.

Studdy Solution

STEP 1

Assumptions
1. The class interval is 95-99.
2. The midpoint of a class interval is the average of the lower and upper class boundaries.

STEP 2

To find the midpoint of the class interval, we add the lower class boundary to the upper class boundary and then divide by 2.
$Midpoint = \frac{Lower\, class\, boundary + Upper\, class\, boundary}{2}$

STEP 3

Now, plug in the given values for the lower and upper class boundaries to calculate the midpoint.
$Midpoint = \frac{95 + 99}{2}$

STEP 4

Calculate the sum of the lower and upper class boundaries.
$95 + 99 = 194$

STEP 5

Now, divide the sum by 2 to find the midpoint.
$Midpoint = \frac{194}{2}$

STEP 6

Calculate the midpoint.
$Midpoint = \frac{194}{2} = 97$
The midpoint of the class 95-99 is 97, which corresponds to option (B).
