Question: (6 points) Researchers from the Journal of Personality and Social Psychology conducted a study to see if men who were professors or medical doctors had different testosterone levels than men in the general population. Medically speaking, it is estimated that the average testosterone level (measured in nanograms per deciliter) for the general adult male population is 10.70. The average testosterone level for the 26 doctors and professors in the study was 11.15, and the standard deviation of the levels was 2.59. Does this sample outcome provide sufficient evidence that the average testosterone level for all male doctors and professors is different than that of the general adult male population? Make your decision using the .05 level of significance.

Using plain language, interpret your statistical decision.
