the data I am given is
y1 = c(7.6,8.2,6.8,5.8,6.9,6.6,6.3,7.7,6.0)
y2 = c(6.7,8.1,9.4,8.6,7.8,7.7,8.9,7.9,8.3,8.7,7.1,8.)
y3 = c(8.5,9.7,10.1,7.8,9.6,9.5)
I am supposed to get a 95% confidence interval of the mean of y3 but the standard error I get in error is effectively nothing am I somehow supposed to get a standard error using the rest of the data set? if so how?
