Problem
A correct sample size has been determined in a work sample study for an operation within a production line. The analysis of the operation is aimed at determining the proportion of idle time expected (p) of the operator. It is known that the desired precision for the study is 3% and a confidence level of 95% has been considered. The deviation of the data is, according to the analyst, 0.035. Given this, check with calculations if the analyst is correct regarding the standard deviation and indicate what is the value of the deviation of the data collected by the analyst for this study that is taken on the work sample.
