You will have to calculate the mean and standard deviation. You will need those values to plug into a confidence interval formula.
If you use a z-table, the formula is:
CI95 = mean + or - 1.96(sd/√n)
...where n = sample size, sd = standard deviation, + or - 1.96 represents the 95% confidence interval using a z-table.
I hope this will help.
how do you get thesampling and confidence intervals for this problem
sample scores of 1,2,3,4,5 and 95 percent confidence interval about the sample mean
