Homework
Create a publication quality plot for each of these case examples. For each plot, indicate inside the plot if that is a case of one, two or more samples:
Chevrolet and Honda are strongly competing to produce hybrid cars as an option to electrical cars. The Honda model drives 50mpg (miles per gallon) +/-5mpg and the Chevrolet model drives 55mpg (miles per gallon) +/-7mpg.
Students at a school got on average GPA of 3.8, and are being considered for an award if they are among the best at the national level, in which the average GPA was 3.5 +/-0.12.
China is currently looking to optimize food production within its borders and run an experiment on biomass production for wheat, rice and corn. The annual yields were 55500 tns +/-500tns for wheat, 45500 tns +/-200tns for rice, and 35500 tns +/-255tns for corn.
Generate only the quality plots, no need to have the code in your report.
