I need with these questions as soon as possible please. Thank you. a. What is the probability of success originally (the null proportion, p0)? b. Is this study one tailed or two tailed?c. what should the value for alpha (a) be for this study?d. For this study what is the number we are interested in (success;x)e. For this study what is the number of trials (k)?

e U.K. a study of surgical site infections found that over a several year period of 67,410 surgeries in the stud 2 were followed by a surgical site infection. After the study measures were taken to try to reduce surgical sit ctions. In a followup study out of 6235 surgeries there were 218 surgical site infections. The researchers nted to know if the measures taken reduced surgical site infections (I know this one seems weird, but go ahead d count infections as "successes" because that's what they're interested in studying). or this study what is the probability of success originally (the null proportion, po)
