	underweight	at goal weight	overweight	total
male	93	206	81	380
female	37	446	137	620
total	130	652	218	1000

(1 point)
13.0%
65.2%
21.8%
68.4%

Explanation:

Step1: Recall marginal - distribution formula

The marginal distribution of a category in a two - way table is the proportion of that category out of the total. For the "At Goal Weight" category, we use the formula $\text{Proportion}=\frac{\text{Number in At Goal Weight}}{\text{Total number of individuals}}$.

Step2: Identify relevant values

The number of individuals at goal weight is 652, and the total number of individuals is 1000.

Step3: Calculate the proportion

$\text{Proportion}=\frac{652}{1000}=0.652$.

Step4: Convert to percentage

$0.652\times100 = 65.2\%$.

Answer:

65.2%
