Problem 1. (3 points) A multinomial experiment with k = 3 cells and n = 320 produced the data shown below. Cell 1 Cell 2 Cell 3 ni 87 70 163 If the null hypothesis is Ho : P1 = .25, p2 = .25, p3 - .5 and using a = 0.05, then do the following: (a) Find the expected value of Cell 1. E(Cell 1) =1 (b) Find the expected value of Cell 2. E(Cell 2) = (c) Find the expected value of Cell 3. E(Cell 3) = (d) Find the test statistic. (e) Find the rejection region. The final conclustion is A. We can reject the null hypothesis that p, - .25, p2 - .25, p3 -.5 and accept that at least one of the multinomial probabilities does B. There is not sufficient evidence to reject the null hypothesis that p, #.25, p2 - .25, p3 - .5. Note: You can earn partial credit on this
