Hi! I'm trying to use sapply to my dataframe for z.test function (teaching demos package) Sep=cbind(kIp,k02p,k04p,k07p) Sep=as.data.frame(Sep) kzt=sapply(Sep, function(m) z.test(m,sd(m))) Error in z.test(m, sd(Sep)) : You must specify a Standard Deviation of the population kzt=sapply(Sep, function(m) z.test(m,sd(Sep))) Error in z.test(m, sd(Sep)) : You must specify a Standard Deviation
