For the first few questions, think about what each part of the procedure does for you.
You can have a:
One sample: (one population, one group of data)
Two Sample: (two populations, a treatment and no treatment, two sets of data)
Matched Pairs: (two sets of data, yet both are on the same individuals).
AND
t-test: sigma unknown
z-test: sigma known
For questions 3-12, we are doing a two sample test because we have men and women scores for the same thing.
Remember, the parameter differs from a one sample. What is the word we need in there that makes it different? HINT: It starts with a "D".
Remember this question is a great way to prepare for the exam written part.
Good Luck!
