The question is in the picture

The city council of Pine Bluffs is considering increasing the number of police in an effort to reduce crime. Before making a final decision, the council asked the chief of police to survey other cities of similar size to determine the relationship between the number of police and the number of crimes reported. A regression analysis was conducted to develop a regression equation to estimate the number of crimes given the number of police. Results of the analysis, based on a sample of 12 observations, are presented below. D=48.17-0.155X Z(x,-X)2 =26156.92 Z(v1- D)2 =825.93 I. The test statistic used to determine whether there is a significant relationship between the variables equals II. The critical value from the table used to test whether there is a significant relationship between the variables at 5% level equals III. Carry out the test to determine if there is a relationship between the variables at the 5% level. What is the appropriate conclusion for this test? a. Reject Ho: There is a significant relationship between the variables. b. Fail to reject Ho: There is insufficient evidence to conclude a significant relationship exists between the variables. c. Fail to reject Ho: There is evidence to conclude that the independent variable is not significant. The letter corresponding to your answer is
