A Professor Wishes to Determine If There Is a Difference

A professor wishes to determine if there is a difference between the average test grades of her students who use the resources available to them with those students who don't use the resources. The Alpha is 0.05 and the P-value is 0.03. She should conclude:

A) Reject the null hypothesis because there is a statistically significant relationship between nursing students' grades and their use of available resources.
B) Fail to reject the null hypothesis. There is not a relationship between nurses' grades and using available resources.
C) Reject the null hypothesis. Nursing students are more likely to use the resources available.
D) Fail to reject the null. The relationship is not clinically significant.
