More generally, the formula for the 95% confidence interval on the mean is: Lower limit = M - (tCL)(sM) Upper limit = M + (tCL)(sM) where M is the sample mean, tCL is the t for the confidence level desired (0.95 in the above example), and sM is the estimated standard error of the mean.
The lower limit for every class is the smallest value in that class. On the other hand, the upper limit for every class is the greatest value in that class. The class midpoint is the lower class limit plus the upper class limit divided by . Simplify all the midpoint column. Add the midpoints column to the original table.
