SB 7.19 normal distribution

Question

19. Which of the following data sets could most likely be normally distributed?

 

a) Number of homeruns per baseball player in a championship series
b) IQ test scores
c) Yearly income for California residents
d) Daily temperatures high for winter in 25 US cities

Answer 1

Due to the fact that a normal distribution is highly dependent on the size of the sample, we would expect the yearly income for California residents to yield a normal distribution.
