Determine the sample size n needed to construct a 95% confidence interval to estimate the population proportion when p=0.42 and the margin of error equals 8%.

n = ____?___ (Round up to the nearest integer.)

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
