(6 marks) b) Is there a gender similarity between colour words? (use a 0.05 significance level) (7 marks) c) Conduct your test in part (b) using the appropriate confidence interval.

(Use a 0.01 significance level) (9 marks) e) Assuming equal variability, is the male colour rectangle times higher than that of the female's by more than 3 seconds? (Use a 0.1 significance level) (9 marks)
