Lower bound of the population mean is 0.328

Upper bound of the population mean is 0.486

Confidence level is 99%

Percent means per one hundred so we can say that:

p/100≈(28)/(28+81+45+63+35) guessing with my old eyes :)

p/100≈28/252

p≈2800/252

p≈11.11%

So rounded to the nearest 5% you'd have:

p≈10%
