IQ Score

Mean - 102

Mode - 100

Median - 100

Variance - 72.1

Standard deviation - 8.49

Standard error of mean -1.44

A)Assume that we know the global population average IQ score is 100 and the population standard deviation is 7.5. Does this sample show a significantly different average IQ? Please give statistical test you used, the value of that test, and the p value.

B)Which distribution is being used in the statistical test administered in Question 1-A? (hint: not the sample's distribution but rather the normal, t, f, chi, etc. distributions)

What are the steps to solve this as well as what test do you use
