A university wants to determine whether a recently hired instructor (Instructor I) is working out. Nineteen (19) out of 30 of “Instructor I” students passed a certain test on the first try. In comparison, 57 out of 72 of more experienced “Instructor II” students passed the test on the first try. Calculate the confidence interval for the difference of the two proportions, defined as: 'proportion (Instructor I) - proportion (Instructor II)' (0.329 , 0.582) (- 0.013 , 0.002) (- 0.355 , 0.038) (- 0.585 , - 0.108)
