The given table in exercise 25 is shown below:

The total number of college students who felt that their body weight was about right: 855

Out of them, females are 500.

Therefore, the required proportion is:

$\frac{560}{855}=\frac{112}{171}\mathrm{or}鈮�0.6550$

The total number of college students who are females is: 760

out of them, 560 females felt that their weight is about right.

Therefore, the required proportion is:

$\frac{560}{760}=73.68\%$

The given bar graph is shown below:

The majority of females believe their body weight is about right, whereas the majority of males believe the same.

As we can see that the blue area of the bars is larger for females, and more females believe their body weight is about right. Because the red area of the bars is greater for ladies than for males, more females believe they are overweight.

As we can see that the green area of the bars is greater for males than for females, more males believe they are underweight.
