3 The Makeup Test 2
Complete a 10-minute video presentation to complete the following four (4) parts:
I. Show a clear picture of your U of T student card.
Using our class population data in the file, mut2data.csv, suppose we want to estimate the
mean height of students in our class using a probability sample of students.
II. Using numbers, formulas and diagrams, demonstrate the similarities and/or differences in using
a simple random sample versus a systematic random sample to estimate the population height
mean. Use sample size n=20.
III. Using numbers, formulas and diagrams, demonstrate the similarities and/or differences in
using ratio, regression and difference estimation based on a simple random sample of n = 10
students to estimate the population height mean.

IV. Using numbers, formulas and diagrams, demonstrate the similarities and/or differences in
using one-stage cluster sampling versus simple random sample to estimate the population
height mean. Use the variable -digits , to form clusters and randomly sample 2 clusters to
make up your cluster sample. For simple random sampling, use the same sample size as that
of your cluster sample.
