Write the class size and class limits in each of the following:
$12.5, 17.5, 22.5, 27.5, 32.5, 37.5, 42.5, 47.5$

Given:

$12.5, 17.5, 22.5, 27.5, 32.5, 37.5, 42.5, 47.5$

To do:

We have to write the class size and class limit.

Solution:

$12.5, 17.5, 22.5, 27.5, 32.5, 37.5, 42.5, 47.5$

Class size $= 17.5 - 12.5$

$= 5$

Class MarkLower class limitUpper class limitClass limit
12.5
$12.5-\frac{5}{2}=10$$12.5+\frac{5}{2}=15$$10-15$
17.5
$17.5-\frac{5}{2}=15$
$17.5+\frac{5}{2}=20$
$15-20$
22.5
$22.5-\frac{5}{2}=20$
$22.5+\frac{5}{2}=25$
$20-25$
27.5
$27.5-\frac{5}{2}=25$
$27.5+\frac{5}{2}=30$
$25-30$
32.5
$32.5-\frac{5}{2}=30$
$32.5+\frac{5}{2}=35$
$30-35$
37.5
$37.5-\frac{5}{2}=35$
$37.5+\frac{5}{2}=40$
$35-40$
42.5
$42.5-\frac{5}{2}=40$
$42.5+\frac{5}{2}=45$
$40-45$
47.5
$47.5-\frac{5}{2}=45$
$47.5+\frac{5}{2}=50$
$45-50$
