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 1 of 2: determine the midpoint for the fifth class.

Explanation:

Step1: Identify fifth class bounds

The fifth class is 0.65-0.74, so lower bound $L=0.65$, upper bound $U=0.74$.

Step2: Calculate class midpoint

Use midpoint formula: $\text{Midpoint} = \frac{L + U}{2}$
$\text{Midpoint} = \frac{0.65 + 0.74}{2} = \frac{1.39}{2}$

Step3: Compute final value

$\frac{1.39}{2} = 0.695$

Answer:

0.695
