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

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 ztable, 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 ztable.
I hope this will help.
