Question

Data were gathered from a simple random sample of cities. The variables are Violent Crime (crimes per 100,000 population), Police Officer Wage (mean $/hr), and Graduation Rate (%). Use the accompanying regression table to answer the following questions considering the coefficient of Police Officer Wage. Complete parts a through d.

Dependent variable is: Violent Crime

R squareds=39.8 % R squared (adjusted)equals=42.1% s=129.6 with 37 degrees of freedom

Variable	Coeff	SE (Coeff)		t-ratio		P-value
Intercept	1388.04	185	.6	7.48		<	0.0001
Police Officer Wage	9.43	4	.271	2.21			0.0335
Graduation Rate	−16.54	2	.500	−6.62		<	0.0001

a) State the standard null and alternative hypotheses for the true coefficient of Police Officer Wage

A) Ho: βOfficer=0

HA: βOfficer>0

B. H0: β Officer does not equal≠0

HA: β Officer=0

C. H0: βOfficer =0

HA: βOfficer<0

D. H0: βOfficer=0

HA: βOfficer≠0 Your answer is correct.

b) What is the t-statistic corresponding to this test?

_______ (Type an integer or a decimal.)
