A) A potential car buyer is undecided on whether to buy a 2012 car with a front-wheel-drive (F) or with a rear-wheel-drive (R). Obtain the fuel efficiency mean, standard deviation, and the number of observations included in the sample for each type of these systems. B) Construct and interpret a 95% confidence interval for the true difference in mean city mileage (MPG) between front wheel drive (F) and rear wheel drive (R) systems. Assume that MPG of front wheel drive and rear wheel drive cars follow a normal distribution. *Note: You can use Excel or Rstudio or any means necessary comb_mpg drive_sys 13 R 16 R 16 R 15 R 16 R 27 R

Question

Use the Data Below:

A potential car buyer is undecided on whether to buy a 2012 car with a front-wheel-drive (F) or with a rear-wheel-drive (R). Obtain the fuel efficiency mean, standard deviation, and the number of observations included in the sample for each type of these systems.

Construct and interpret a 95% confidence interval for the true difference in
mean city mileage (MPG) between front wheel drive (F) and rear wheel drive (R) systems. Assume that MPG of front wheel drive and rear wheel drive cars follow a normal distribution.

*Note: You can use Excel or Rstudio or any means necessary

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
