Method #5: Stratified Random Sample In Happyville, it appears that households on the north side of the river have more residents than those on the south side of the river. Note that 40% of the households are located on the north side. A reasonable approach is make sure that 40% of the households sampled are on the north side, rn a sample of size 10, that means 4 households from the north side. To take a stratified random sample, we divide our populatioh into layers or strata, in this case the two sides of town. Then we take separate random samples from each side. In this case, we will take a sample of 4 from the north and a sample of 6 from the south. Below are some samples that were generated using Minitab. Your team will pick one of the North samples and one of the South samples randomly and find the overall mean. Here is the procedure: Use the first digit of your UA ID. If between 1-5, pick the corresponding North sample. If 6 pick Northl, 7North2, 8(North3, 9:North4, 0:North5. Now use the second digit of your UA ID to select a South Sample in the same fashion.
