Question

Suppose that the scores of architects on a particular creativity test are normally distributed. Using a normal curve table, what percentage of architects have Z-scores:

Above .10 =
Below .10 =
Above .20 =
Below .20 =
Above 1.10 =
Below 1.10 =
Above -.10 =
Below -.10 =

Answer 1

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportions/probabilities related to the Z scores. Multiply each by 100 to get percentages.

I assume you can find the table. We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
