Assume that independent random samples were taken from populations that were normally distributed and that the populations have equal variances. 4. Choose the best answer below concerning the confidence interval for the difference between the annual amount of paid leave by Group A miners the annual amount of paid leave by Group B. b) (A-A)-2, (-A), A(I-A) d) (X - 1)+1 IS.S 5. Assuming that the confidence coofficiant is 90%%, then choose from the following concerning the z- value or I-value that would be used in the Interval. 0) 1.89 B) 1.77 C) 1.68 d) 1.96
