Answer to Question 1

D
The first thing the clustering routine does is take the raw data and standardize it.

Answer to Question 2

A Z-test for differences of proportions is a technique used to test the hypothesis that proportions are significantly different for two independent samples or groups. The test is appropriate for a hypothesis of this form: 1 = 2, which may be restated as 1 - 2 = 0.
