The samples are obtained independently using simple random sampling. ASSUME YES.
The populations from which the samples are drawn are normally distributed OR the
sample sizes are large (n,2 30, n, 2 30).
For each sample, the sample size is no more than 5% of the population size.
Step 4: We recall that the level of significance is a =
