Use RStudio to solve. The Indy 500 is one of America’s most watched motorsport events. Recently, my friend and I were talking about the average speed (mph) of the fastest lap over the last 20 years. We think the average fast lap speed in the last 20 years was around 220 mph. Below are the fast lap times from 1996-2016. Is the real average significantly faster or slower that what we guessed? Please be specific with your answer.
236.1, 215.6, 214.7, 218.8, 218.4, 219.8, 226.5, 229.1, 218.4, 228.1, 221.2, 223.4, 224.0, 222.2, 225.0, 220.1, 226.9, 225.1, 226.7, 225.3
So, there is sufficient evidence to support the claim that the real average significantly faster than what we guessed.
