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.
Update: since class interval is 11 so classes must have a difference of 11 if we do upper-lower so if i start from 22 upto 33 33 upto 44 44 upto 55 55 upto 66 66 upto 77 77 upto ... show more since class interval is 11 so classes must have a difference of 11 if we do upper-lower. so if i start from 22 upto 33.
