2. The Welcher Adult Intelligence Test Scale is composed of a number of subtests. On one subtest, the raw scores have a mean of 35 and a standard deviation of 6. Assuming these raw scores form a normal distribution:What number represents the 65^th percentile (what number separates the lower 65% of the distribution)?

I am looking for an answer that does not include the table/chart associated. Strange I know but this is how I have been asked to calculate.
