Question

Find the probability that a data value picked at random from a normally distributed population will have a standard score that corresponds to the following:

Less than 3.00

Answer 1

It depends on what you define as a 'normally distributed population'.

Answer 2

not when it is a standard normal distribution, which I thnk he implied. The 3 is a z score, I think, so you go to the z score chart and see what percentage of the area falls under 3. The answer is 99.865.
