You find 5 male friends at the U of C and find that they spent an average of $680 with a standard deviation of $5. You find 4 female friends at the U of C and find that they spent an average of $690 with a standard deviation of $7. Is there a statistically significant difference in the average amount spent between the male and female friends (at α = .05)?
