Question

Question 5 (1 point)

It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test the hypothesis that students who study one week before score less than students who study the night before. A hypothesis test for two independent samples is run based on your data and a p-value is calculated to be 0.6899. What is the appropriate conclusion?

Question 5 options:

1)	We did not find enough evidence to say the average score of students who study one week before a test is greater than the average score of students who wait to study until the night before a test.

2)	The average score of students who study one week before a test is significantly less than the average score of students who wait to study until the night before a test.

3)	We did not find enough evidence to say a significant difference exists between the average score of students who study one week before a test and the average score of students who wait to study until the night before a test.

4)	The average score of students who study one week before a test is greater than or equal to the average score of students who wait to study until the night before a test.

5)	We did not find enough evidence to say the average score of students who study one week before a test is less than the average score of students who wait to study until the night before a test.

Answer 1

Given that we have to test the hypothesis for the following statement

"students who study one week before score less than students who study the night before"

So, we are testing right tailed hypothesis

It is given that the p value is 0.6899

We can see that the p value is greater than significance level of 0.05 or 0.10.

this means that the result is insignificant and we failed to reject the null hypothesis

therefore, we can say that there is insufficient evidence to conclude that students who study one week before score less than students who study the night before.

option (5) is correct
