Question

At a concert, a survey was conducted that asked a random sample of 100 people their age and how many concerts they have attended last year. A regression model is estimated and the Excel output follows:

	df	SS	MS	F	Significant F
Regression	1	107.50	107.50	53.55	0.00
Residual	98	196.74	2.01
Total	99	304.24

	Coefficients	Standard Error	t Stat	P-value	Lower 95%	Upper 95%
Intercept	-2.37	0.57	-4.15	0.00	-3.50	-1.24
Age	0.11	0.02	7.32	0.00	0.08	0.14

Find the coefficient of determination (also known as R-square) of this regression.

	a.	0.5044
	b.	0.3533
	c.	0.2359
	d.	0.5965
