Does the frequency distribution appear to have a normal distribution using a strict interpretation of the relevant criteria?

IQ Score------Frequency
50-69----------24
79-89----------228
90-109--------490
110-129--------232
130-149-------26

a. Yes, all the requirements are met.
b. No, the frequencies do not decrease from the maximum frequency to a low frequency.
c. No, the distribution does not appear to be normal.
