tudents sometimes suspect that studying more isn't worth it for "harder" math and science classes: either you understand it, or you don't. To find out whether more studying actually transferred to higher grades, one enterprising student surveyed randomly selected students and asked them the number of hours they had spent studying for a final exam in a core math or science class, and their grade on the final exam. The student wanted to know the average increase in points scored on the final for every additional hour spent studying. What statistical procedure should be performed?

Answer:

Hi your question lacks the required options here are the options:

a. 2 proportion z-test

b. regression

c. 2 independent samples t-test

d. matched pairs t-test

e. 1 proportion z-test

The statistical procedure that should be performed is regression ( B )

Step-by-step explanation:

The student wanting to know the average increase in points scored on the final for every additional hour spent studying can be achieved more accurately by performing a regression procedure

A regression test is used to determine the strength relationship between an dependent variable in an experiment with other variables ( independent )in the experiment. in the question the student wants to know the strength of relationship between the increase in points and additional hour spent studying. there regression is the best statistical procedure to use.
