A company manufacturing CDs is working on a new technology. A random sample of 646 Internet users were asked: "As you mayknow, some CDs are being manufactured so that you can only make one copy of the CD after you purchase it. Would you buy aCD with this technology, or would you refuse to buy it even if it was one you would normally buy?" Of these users, 59% respondedthat they would buy the CD. Complete parts a and b below.a) Create a 99% confidence interval for this percentage.( 54.008 %, 63.993 %)(Round to three decimal places as needed. Use ascending order.)b) If the company wants to cut the margin of error by two thirds, how many users must they survey?The company must survey a total of(Type a whole number.)users

here from given information p = proportion of user who would buy CD = 0.59
