this is the problem:
we wish to estimate the mean execution time of a program. the program was run 35 times on randomly selected inputs, and the sample mean and the sample standard deviation of the execution times were evaluated as (x bar)=230ms, and S(sample sd)=14ms, respectively. find 95% CI for the true mean execution time u
what and how can you tell this is a non-normal population. i knew it because it is an example under "Large sample CI for non-normal population"
