5. (5.12) Suppose y=0 at x=0, 10,20,30Ay=1atx=70, 80,90,100. Use R a. Explain intuitively why B= for the model, logit P(Y =1))=a+Bx. Report B and its SE for the software you use. b. Add two observations at x = 50, y = 1 for one and y = 0 for the other. Report B and its SE. Do you think these are correct? Why? What happens if you replace the two observations by y = 1 at x = 49.9 and y = 0 at x = 50.1
