Use the following information for questions:
A study compared grade point averages (GPA) for students in a class: students were divided by 6 locations where they usually sat during lecture (i.e. left or right front, left or right center, left or right rear). A total sample size of 12 students was studied (2 students from each section) using one-way analysis of variance.
-The p-value for the F-test is 0.46. If the significance level = 0.05, what is the conclusion?
A) The null hypothesis is not rejected so we cannot say the population means are different.
B) The null hypothesis is not rejected so we can say the population means are different.
C) The null hypothesis is rejected so we cannot say the population means are different.
D) The null hypothesis is rejected so we can say the population means are different.

The p-value of 0.46 is greater than the significance level of 0.05, indicating that there is not enough evidence to reject the null hypothesis. Therefore, we cannot conclude that there are differences in the population means based on seating location.
