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%

i dont know

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
