random sample of size 28 is taken from the adult population of Australia, calculate the
probability that less than 16% of the adults in this sample have hazel colored eyes.
A. 0.0001
B. 0.7019
C. This cannot be done because we can't assume that the sampling distribution of p-hat is
normal because n is not greater than 30.
