A human resources study claims that the average age of Canadians who retire is 68 years. You believe that the average age is less than that. You take a random sample of 44 Canadians who have retired, and find their average age to be 67.6 years, with a standard deviation of 0.90 years. Using the resulting p-value of 0.0016, you conclude that this is significantly lower than the age of 68 stated in the study. What would be the most appropriate interpretation of this result?
