Hi. I'm trying to create an Agresti-Coull confidence interval without using the binom package. Despite many trials, I keep getting the same problem- see below. > y=334 > n=1160 > alpha=.05 > b=(y+.5*qnorm(1-alpha/2)**2)/(n+qnorm(1-alpha/2)**2) > b [1] 0.288631 > ac=b+qnorm(1-alpha/2)*sqrt(b(1-b)/(n+qnorm(1-alpha/2)**2)) Error: could not find function "b"
What am I missing? What am I doing wrong?
