The city of Pine Bluffs is studying the relationship between the number of police officers employed by the city and the number of crimes committed. The city council surveyed a random sample of other cities similar to Pine Bluffs to gather data on the number of crimes committed during a specified time period and the number of police officers the city employed. The results of an analysis of the data are shown below. The regression equation is Number of Crimes Predictor Constant Police 29.388 0.9596 Police Coef 29.388 SE Coef 4.143 T P-Value 7.09 0.000 -0.9596 0.2174 -4.41 0.004 What is the null hypothesis corresponding to the p-value of 0.004? (A) Changing the number of police affects the number of crimes for all cities like Pine Bluffs. (B) There is a linear relationship between the number of police and the number of crimes for all cities like Pine Bluffs. (C) There is no linear relationship between the number of police and the number of crimes for all cities like Pine Bluffs. (D) There is no relationship between the number of police and the number of crimes for all cities like Pine Bluffs. (E) There is no difference between the mean number of police and the mean number of crimes for all cities like Pine Bluffs.

A consumer advocacy group recorded several variables on 140 models of cars. The resulting information was used to produce the following regression output that relates the city gas mileage (in mpg) and the engine displacement (in cubic inches). The regression equation is mpg_city= 35.5 - 0.0696 * displacement We have a car that has an engine with 141 cubic inches. Based on this output, what city gas mileage would you predict for this car?____ (Round answer to the nearest hundredth (2 decimal places.)

To monitor and improve its productivity, a company made an investigation and found out that the factor that affects the productivity the most is the absenteeism. The company data analytics department have collected data about the two variables (Productivity and Absenteeism) for the 12 past years as shown in the table below. Now the purpose of the company is to determine, through regression analysis, whether the productivity is statistically affected by the absenteeism level or not.
