Question

Construct the 90% confidence interval estimate of the population proportion p if the sample size is n=400 and the number of successes in the sample is x=87.

__<p<__

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.
