(i) A principal components analysis in JASP Interpret the output. [3 marks]
(ii) A maximum likelihood factor analysis in JASP. (do not use the factor solution from part (i)) Interpret the output. [3 marks]
b. JASP input and output files. [3 marks]
Question 2
ABL motors has hired a consultant to determine if the CO2 emissions and diesel consumption of automobiles differ based on the number of engine cylinders in that automobile. You collect data on diesel consumption of an automobile (fuel), the CO2 emissions of an automobile (CO2) and the number of cylinders in the automobile engine (cylinders), either 4, 8, or 10. The dataset includes 300 observations. The data with the results can be found in the sheet labelled "Question 2".
a. Conduct the relevant test to determine if the CO2 emissions and diesel consumption of automobiles differ based on the number of engine cylinders in that automobile [6 marks]
b. Test the relevant assumptions associated with this test. [4 marks] c. JASP input and output files. [3 marks]
