Question

consider the following frequency table representing the distribution of the weight of a hamburger patty (in pounds)
weight of a hamburger (in pounds)
class frequency
0.25–0.34 11
0.35–0.44 14
0.45–0.54 3
0.55–0.64 10
0.65–0.74 4
step 2 of 2: determine the midpoint for the fourth class.

Explanation:

Step1: Identify fourth class bounds

The fourth class is 0.55–0.64, so lower bound $L=0.55$, upper bound $U=0.64$.

Step2: Calculate midpoint

Use midpoint formula: $\text{Midpoint} = \frac{L + U}{2}$
$\text{Midpoint} = \frac{0.55 + 0.64}{2}$

Step3: Compute the value

$\text{Midpoint} = \frac{1.19}{2} = 0.595$

Answer:

0.595
