May 22, 200917 yr If i have the sample size (31), mean(50) and the standard deviation(4), what analysis do i use to plot the two sided confidence interval of 95 %, in minitab? (Assuming data is normal)
May 26, 200917 yr Dear Biswajit,Use Stat->Basic Statistics -> 1-Sample t (Make sure you use Summarized data to feed in your values). This should give you the required 2-sided confidence intervals in the session window.SJ.
