Challenge Problems
Push your limits with challenges.
Question 1
You conduct a study with two groups. Group A (n=100, \bar{x}=85, \sigma=10) and Group B (n=100, \bar{x}=82, \sigma=15). Using a 0.05 significance level, determine whether the difference in means is significant.
💡 Hint: Don't forget to compute the combined standard deviations!
