A prior study determined the point estimate of the population proportion as 58% ( = 0.58). The analysts decide to conduct a second study on the same topic and would like its margin of error, E, to be 4% when its confidence level is 95% (z*-score of 1.96).

What is the minimum sample size that should be used so the estimate of will be within the required margin of error of the population proportion?

Minimum Sample size  'n' = 585

Step-by-step explanation:

Explanation:-

Given Estimate of the population proportion as 58% ( = 0.58)

P = 0.58

Given margin of error, E, to be 4%

M.E = 4 % = 0.04

margin of error of the population proportion is determined by

Z- score = 1.96

Cross multiplication , we get

Squaring on both sides, we get

n = 584.7≅585

Conclusion:-

minimum Sample size  'n' = 585

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
