A newspaper article claims that the average age for people who receive food stamps is 40 years. You believe that the average age is less than that. You take a random sample of 100 people who receive food stamps, and find their average age to be 39.2 years. You find that the calculated test statistic falls within the rejection zone (assuming α = .05). What would be an appropriate interpretation of this result?
The statistically significant result indicates that the average age of people who receive food stamps is younger than 40.
The evidence is not strong enough to support the claim that the average age of people who receive food stamps is younger than 40.
An error must have been made. This difference is too small to be statistically significant.
