The manufacturers of a new model of car state that, when travelling at 56 miles per hour, the petrol consumption has a mean value of 32.4 miles per gallon with a standard deviation of 1.4 miles per gallon. Assuming a normal distribution, a) calculate the probability that a randomly chosen car of that model will have a petrol consumption greater than 30 miles per gallon when travelling at 56 miles per hour. b) Using R Studio to verify the probability in part a) above.
