The Environmental Protection Agency (EPA) fuel economy estimates for automobile models tested recently predicted a mean of 24.8 mpg and a standard deviation of 6.2 mpg for highway driving. Assume that a Normal model can be applied. a) Draw the model for auto fuel economy. Clearly label it, showing what the 68-95-97 Rule predicts. Use StatCrunch, Excel, or Minitab. b) In what interval would you expect the central 68% of autos to be found? c) About what percent of autos...

A researcher proposes to model daily coffee consumption among college students by a normal distribution with mean 20 oz and a standard deviation 4 oz. What is the probability that a randomly selected student will have coffee consumption in the range [mean-SD, mean+SD]? 2. Verify your answer by using R. Generate 1 million random samples from the normal distribution with appropriate mean and SD. Does the normal distribution is in between[ 20-4, 20+4]?? For the R code will that be...
