An instructor wants to show the students that there is a linear correlation between the number of hours they spent watching TV during a certain weekend and their scores on a test taken the following Monday. The number of television viewing hours and the test scores for 12 randomly selected students are shown in the table below.

Hours (x)	0	1	2	3	3	5	5	5	6	7	7	10
Score (y)	96	85	82	74	95	68	76	84	58	65	75	50

• Correlation coefficientis: r =
• The equation of regression line is: Score = *(Hours) +
• Coefficient of determination:

Test the significance of the correlation coefficient using = 0.05and the claim< 0.

• H₀:>0
• H_a:<0
• = 0.05
• n=12
• df=
