What sample size is needed to give a margin of error within plus-or-minus 5% in estimating a population proportion with 90% confidence? use z-values rounded to three decimal places. round your answer up to the nearest integer. sample sizeequals the absolute tolerance is +/-5

271.

Step-by-step explanation:

When the prior population proportion of success is not available, then the formula to find the sample size is given by :-

Given : Significance level :

By using the standard normal distribution table ,

Critical value :

Margin of error :

Then , the required minimum sample size will be :-

Hence, the required minimum sample size is 271.
