PART A. An experimenter would like to test the effects of estrogen on maze learning in female lab rats. It is known that ovariectomized animals, without estrogen, take p = 20 trials on average to learn a maze with o = 1.358. When progesterone levels are high, female rats take [1 = 16 trials on average to learn a maze with o = 1.995. Previous work suggests that estrogen will lead to longer maze solving times, and the improvement is associated with an effect size of 0.29600. The experimenter would like to conduct a one-tailed 2 test with d = .05. How many subjects would be required to achieve power = .80. Show the following quantities for the required sample size. a. B |:| (1 mark) b. 6 |:| (1 mark) 0. n |:| (4 marks)
