A quality-conscious disk manufacturer wishes to know the fraction of disks his company makes which are defective. Suppose a sample of 865 floppy disks is drawn. Of these disks, 112 were defective. Using the data, estimate the proportion of disks which are defective rounded to three decimal places. Use the data as well to construct the 95% confidence interval for population proportion of disks which are defective rounded to 3 decimal places
