-The 95% confidence interval based on this data is 0.0742 to 0.1302. Which of the following is the correct interpretation?

• A) The percentage of electronic components that are to be reworked is between 7.42% and 13.02%.
• B) We are 95% confident that between 7.42% and 13.02% of electrical components are to be reworked.
• C) The margin of error for the true percentage of electrical components that are reworked is between 7.42% and 13.02%.
• D) All samples of size 450 will yield a percentage of reworked electrical components that falls within 7.42% and 13.02%.
• E) The probability that the true number of electrical parts that have to be reworked is between 7.42% and 13.02% is 0.05.
