Answer:
The requirements for the hypothesis test does satisfied the method for testing the claim that from two population proportions the rate of polio is less for children given the salk vaccine.
Step-by-step explanation:
The percentage of children in the treatment group was:
(201229/401974)*100 = 49.9%
The percentage of children given placebo was:
(200745/401974)*100 = 50.1%
The percentage of children that developed polio in the treatment group:
(33/200745)*100 = 0.0164%
The percentage of children that developed polio in the placebo group:
(115/201229)*100 = 0.0571%
The percentage difference between the two group:
((0.0571-0.0164)/0.0571) = 61.62%
Therefore:
The amount of children used for each group was almost divided into half of the total amount of children. The test revealed although very small percentages of the both group developed polio, 68.62% more children given placebo than the children that was given the salk vaccine. Therefore, the study shows that the rate of polio is less for children given the salk vaccine and the the hypthesis test is satisfied.

This problem bothers on the mensuration of flat shapes, composite rectangle. </h2>
The correct method for finding the area of a composite rectangle with a large rectangle and a small rectangle connected on the right side are highlighted below.
also see attached the rough sketch of the two rectangles.
- Decompose the figure into two rectangles and add the areas
- Extend the top and rightmost sides to make a larger rectangle, find its area, and then subtract the area of the removed corner.
- Decompose the figure into two rectangles, find their sum, and then subtract the area of the removed corner.
