The margin of error (MOE) for a survey tells you how near you can expect the survey results to be to the correctpopulationvalue. For example, a survey indicates that 72% of respondents favor Brand A over Brand B with a 3% margin of error. In this case, the actual population percentage...
Margin of Error = Z * √((p * (1 – p)) / n) Where: p– Sample Proportion (fraction of sample which is a success) Now to find the desiredz score, you need to know the confidence interval of the sample because the Z score depends on that. The below table is given to see the...

given equation of a line is: y – 7 = -3(x – 11) comparing the above equation with y – y 1 = m(x – x 1 ) m = -3 (x 1 , y 1 ) = (11, 7) therefore, slope is -3 and the point is (11, 7). formulas related links margin of error formula cube formula percentage...
call this variable p. With a 5 percent margin of error (ME) and a z-score (z) of 1.96, our formula for sample size translates from: sample size = (z^2 * (p(1-p)))/ME^2 to sample size = (1.96^2 * (0.5(1-0.5)))/0.05^2. Working through the equation, we move to (3.84...
