A random sample of 83 bicycle enthusiasts found the mean number of miles ridden over the summeris 684 with a standard deviation of 154.5. The 90% confidence interval for the true mean number ofmiles ridden over the summer for all bicycle enthusiasts is (655.79, 712.21). Which statement belowis the correct interpretation of the confidence level?(A) There is a 90% chance the true mean number of miles ridden is between 655.79 and 712.21.(B) 90% of all bicycle enthusiasts ride between 655.79 and 712.21 miles over the summer.(C) We are 90% confident that a randomly selected cyclist will ride between 655.79 and 712.21 milesover the summer.(D) If 50 random samples of size n=83 were taken from the population of bicycle enthusiasts and a90% confidence interval was calculated for each sample, then the true mean number of milesridden would be contained within 45 of the calculated intervals, on average.(E) In repeated sampling, the mean number of miles ridden over the summer will be contained withinthe interval 90% of the time.
