(1 point) A random sample of 120 observations is selected from a binomial population with unknown probability of success pl. The computed value of øl is 0.8. (1) . Test H, : p= 0.55| against H, : p > 0.55). Use a = 0.011. test statistic z= critical score The final conclusion is O A. We can reject the null hypothesis that p = 0.55% and accept that p > 0.55). B. There is not sufficient evidence to reject the null hypothesis that p= 0.55. (2) . Test H. :p= 0.5| against H, :p<0.5. Use a = 0.05. test statistic z= critical score The final conclusion is = O A. There is not sufficient evidence to reject the null hypothesis that p 0.51 B. We can reject the null hypothesis that p= 0.5 and accept that p<0.5). (3) . Test H, : p= 0.6| against H, :P0.6. Use a = 0.05). test statistic z= positive critical zl score. negative critical score The final conclusion is O A. We can reject the null hypothesis that p= 0.6 and accept that p + 0.6. OB. There is not sufficient evidence to reject the null hypothesis that p= 0.61
