A pollster wishes to estimate the proportion of United States voters who favor capital punishment. How large a sample is needed in order to be 9898% confident that the sample proportion will not differ from the true proportion by more than 55%?

Sample size, n = 543

Step-by-step explanation:

We are given the following in the question:

Margin of error = 5%

Confidence interval:

Margin of error =

Since no particular proportion is given, we take

Putting values, we get,

Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
