A random sample of students at Spectrum University was asked to estimate the average number of minutes they spent on social media per day and their grade point average (GPA). The data are shown in the table: Minutes Spent on Social Media 35 58 61 64 72 75 79 101 115
Grade Point Average 3.9 3.6 3.55 3.5 3.2 3.5 3 2.8 2.5

A researcher wants to determine whether there is a relationship between the number of minutes spent on social media each day and GPA. What are the appropriate testing hypotheses? (4 points)
A. H0: β = 0, Ha: β > 0
B. H0: β = 0, Ha: β < 0
C. H0: β = 0, Ha: β ≠ 0
D. H0: β ≠ 0, Ha: β > 0
E. H0: β ≠ 0, Ha: β < 0
