In order to investigate this the company randomly tested n disks and found that 6.85% were defective. Find the appropriate sample size necessary to achieve a margin of error of 0.046 in order to construct a 90% confidence interval for the proportion of all flash disks that are defective. Round your answer to the nearest integer (whole number).
