Statistics

In a survey, the guess at the mean age for the class had a mean of 21.9 and a standard deviation of 3.03.

Given that Normally distributed populations have a first quartile of Z=-0.67 and a third quartile of Z=.67, what does this suggest about whether or not these guesses are normally distributed? The actual first quartile is 20 and the third is 23.

I am so lost i don't know how to do the steps or if a Z scored formula should even be applied. Thank you
