**CJ**, Wednesday, April 28, 2010 at 2:13pmThe applet is great! But I wonder, given the information I have, can I assume that the distribution is normal? (The mean IQ among members of a club is 118 with a standard deviation of 9.46. What percentage of the members had IQ scores of 115 or higher?) If it isn't normal - I can't determine the percentage ... or can I?
