The following data said represented high, feel fancy in miles per gallon and PG a randomly selected cars from two car companies which company has cars that have more consistent and high field efficient car company a 35,28 35, 30, 31,36, 3530 car company B 29, 3030 4027, 34,34, 3425
To determine which car company has more consistent and high fuel-efficient cars, we can calculate the mean and standard deviation of the miles per gallon (MPG) for each car company.
Car Company A:
Mean MPG = (35 + 28 + 35 + 30 + 31 + 36 + 35 + 30) / 8 = 32.375
Standard Deviation = √[ ( (35-32.375)^2 + (28-32.375)^2 + (35-32.375)^2 + (30-32.375)^2 + (31-32.375)^2 + (36-32.375)^2 + (35-32.375)^2 + (30-32.375)^2 ) / 8 ] = 2.641
Car Company B:
Mean MPG = (29 + 30 + 30 + 40 + 27 + 34 + 34 + 34 + 34 + 25) / 10 = 31.7
Standard Deviation = √[ ( (29-31.7)^2 + (30-31.7)^2 + (30-31.7)^2 + (40-31.7)^2 + (27-31.7)^2 + (34-31.7)^2 + (34-31.7)^2 + (34-31.7)^2 + (34-31.7)^2 + (25-31.7)^2 ) / 10 ] = 4.152
Based on the calculations, Car Company A has a higher mean MPG (32.375) compared to Car Company B (31.7) and also has a lower standard deviation (2.641) compared to Car Company B (4.152). This indicates that Car Company A has more consistent and high fuel-efficient cars.
