Chi-square test for independence.

Explanation of Solution

Given:

A brokerage firm wants to see whether the type of account a customer has (Silver, Gold, or Platinum) affects the type of trades that customer makes (in per-son, by phone, or on the Internet). It collects a random sample of trades made for its customers over the past year and performs a test.

Here, researcher wants to check relationship between two variables. Therefore, when there are independent two variables then Chi-square test for independence would be appropriate to use.

b)

Other test.

Explanation of Solution

Given:

That brokerage firm also wants to know if the type of account affects the size of the account (in dollars). It performs a test to see if the mean size of the account is the same for the three account types.

Chi-square test would be appropriate when the variables are categorical. Here, the size of the accounts is in dollar which is quantitative. Hence, other test would be useful.
