Scores on a test are normally distributed with a mean of 60.6 and a standard deviation of 10.3. find P81, which separates the bottom 81% from the top 19%

Is it 0.291 or 69.7 or 63.6 or 0.88 ? Please help

There are two obviously wrong answers and you should be able to calculate the 81st percentile.

What did you get from your calculations?
