Answer 1

3.

We need to check if the type of instruction and intelligence level affects the score. The type of instructions are either traditional lecture and individualized method.

The intelligence level can be classified into high and low intelligence.

This is a case of multiple regression where the class score is a dependent variable(Y) and intelligence level and type of instructions are independent variables.

Option B is the right answer.

4.

This can be done using a hypothesis testing.

A t-test would be suitable here. Creating the null and alternate hypotheses and then rejecting or accepting the null hypothesis on the basis of critical value and area of rejection.

Option B is the right answer.
