An article reports that men over 6 feet tall earn more than men under 6 feet, with these numbers: average 6 foot plus male’s salary $55,000, average male’s salary under 6 foot tall of $47,000, with a p-value of 0.45. Based on that reported p-value, and using the common definition of "statistical significance," which is the case?   With that p value, the results are not significant.    With that p value, the differences are very close, but not statistically significant.   The salary differences are not statistically significant.   The salary differences are statistically significant.
