WebSo instead, you would say my confidence interval is going to be x bar sub one minus x bar sub two plus or minus a critical t value, instead of a z value. Because that works better when you are estimating standard deviation of the sampling distribution of the difference between the sample means. WebSolution: To find the sample size, we need to find the z z -score for the 95% confidence interval. This means that we need to find the z z -score so that the entire area to the left of z z is 0.95 + 1− 0.95 2 = 0.975 0.95 + 1 − 0.95 2 = 0.975. Function. norm.s.inv. chicago spring break packages
