Part 1: Simulation Exercise
Overview From the instructions: In this project you will investigate the exponential distribution in R and compare it with the Central Limit Theorem. The exponential distribution can be simulated in R with rexp(n, lambda) where lambda is the rate parameter. The mean of exponential distribution is 1/lambda and the standard deviation is also 1/lam...

mtcars regression models
Summary The purpose of this analysis is to find if fuel efficiency (miles / gallorn) is affected by transmission type (automatic vs. manual) and, if yes, by how much. The R dataset, ‘mtcars’ contains data from 32 cars (each row has 10 columns). I found that a manual transmission significantly increased fuel efficiency by approximatibely 7.24...
