In a sample of 70 stores of a certain company, 58 violated ascanner accuracy standard. It has been demonstrated that theconditions for a valid large-sample confidence interval for thetrue proportion of the stores that violate the standard were notmet. Determine the number of stores that must be sampled in orderto estimate the true proportion to within 0.04 with 90% confidenceusing the large-sample method. The number of stores that must besampled is
