Question
Use the acompany ng Data were gathered from a simple andom sample of cities. The variables are Violent C e crimes per 100,000 population Police Officer Wage (moan Shr), and Graduation Rate % regression table to answer the following questions considering the coefficilent of Police Officer Wage. Complete parts a through d. Click to view the regression table. a) State the standard null and altemative hypotheses for the true coefficient of Police Officer Wage. i Regression Table Dependent variable is: Violent Crime Rsquared#39.0% Rsquared (adjusted) #41.2% 5 129.6 with 37 degrees of freedom OD, Ho:Potter #0 Variable Intercept Police Officer Wage Graduation Rate Coeff SE (Coeff t-ratio P-value 7.44Explanation / Answer
Ans: The null hypothesis states that the slope is equal to zero, and the alternative hypothesis states that the slope is not equal to zero.
Option D is correct.
t-statistic for regression:
t = b1 / SE
if b1 is negative,t-score will be negative .So,Option D is correct.
p-value is 0.0342
So, option A is correct.
As,p-value <0.05,we reject the null hypothesis.
So,there is sufficient evidence that cofficient is different from zero.
Option B is correct.
Hope this will be helpful thanks and God Bless you>-)
