Question

(07.05)

A random sample of students at Bright University was asked to estimate the average number of minutes they spent online gaming per day and their SAT score. The data are shown in the table.

Minutes Spent Gaming Online	38	43	57	68	75	78	81	100	109
SAT Score	1320	1210	1190	1100	1000	980	960	950	830

A researcher wants to determine whether there is a negative relationship between the number of minutes spent gaming online each day and SAT score. What are the appropriate testing hypotheses? (4 points)

		H0: β = 0, Ha: β > 0
		H0: β = 0, Ha: β < 0
		H0: β = 0, Ha: β ≠ 0
		H0: β ≠ 0, Ha: β > 0
		H0: β ≠ 0, Ha: β < 0
