In order to get the best t line, We will use the midpoint of each of the above Age intervals as follows: Age Number of Driver Deaths per 100,000 1?.5 38 22 36 29.5 24 44.5 20 64.5 18 80 28 Use \"ages" as the independent variable and \"Number of driver deaths per 100.000" as the dependent variable.Answer from your excel sheet: a. Is it signicant? vest'no b. Based on the given data. is there a linear relationship between age of a driver and driver fatality rate? yesfno c. What is the slope of the least squares (bestt) line? To 2 decimal places. d. Interpret the slope by lling in the blanks: As the age group increases by 1. the annual number of drivers deaths (increases or decreases) by QUESTION '9 Use the PREVIOUS PROBLEM and your excel sheet{s} to answer these questions: Recenyhe annual number of driver deaths per 100000 for the selected age groups was as follows: Age Number of Driver Deaths per 100,000 16-19 38 20-24 35 25-34 24 35-54 20 55-74 18 T5+ 28 In order to get the best t line, We will use the midpoint of each of the above Age intervals as follows
