It is hypothesized that the population mean income for nurses is
72,500. A sample of 144 nurses was taken with a mean of 71,500 with
a sample standard deviation of 4,500. Conducting a hypothesis test
with signifigance of 0.05. Why is the following true?
The salary of 71500 is statistically different
from 72500 at a significance of 0.05 because the p-value is
0.0076
