A Hi-Tech company has introduced a new fash disk. Some dealers and customers have complained that some of the new disks are defective. In order to investigate this the company randomly tested 300 disks and found that 30 were defective. A 99% confidence interval for the proportion of all fash disks that are defective was (5.54%, 14.46%). Which one of the following statements is the correct interpretation of the results? O We are 99% confident that (5.54%, 14.46%) contains the true population proportion. O None of these are true. O With probability 99%, the confidence interval (5.54%, 14.46%) contains the true population proportion. Of all the fash disks 99% of the fash disks in the sample are defective between 5.54% and 14.46%.
