A random sample of 83 bicycle enthusiasts found the mean number of miles ridden over the summer is 684 with a standard deviation of 154.5. The 90% confidence interval for the true mean number of miles ridden over the summer for all bicycle enthusiasts is (655.79, 712.21). Which statement below is 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 miles over the summer. (D) If 50 random samples of size n=83 were taken from the population of bicycle enthusiasts and a 90% confidence interval was calculated for each sample, then the true mean number of miles ridden 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…
In a random sample of 8 people, the mean commute time to work was 34.5 minutes and the standard deviation was 7.3 minutes. A 98% confidence interval using the t-distribution was calculated to be (26.8,42.2). After researching commute times to work, it was found that the population standard deviation is 8.7 minutes. Find the margin of error and construct a 98% confidence interval using the standard normal distribution with the appropriate calculations for a standard deviation that is known. Compare the results.
