Interpret your answer.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…A recent poll of 450 college-age students found that 270 agreed with U.S. foreign policy toward Israel.

- A sample of 1200 females and 1000 males found that 78.3% of females and 35.1% males supported increased funding of arts. Construct a 90% confidence interval around the difference in proportions.I need help solving this problem.A research company has carried out a poll to find out about people’s economic outlook. 894 of 1854 young adults (aged between 20–29 years) said that the economic situation is likely to improve over the next year. By contrast, 1292 of 2243 mature adults (aged between 30–39 years) agreed with this statement.) Calculate the upper limit of an 80% confidence interval for the difference between the proportions of people holding this optimistic view in the two age groups in the population. Form the confidence interval around a positive point estimate for the difference between the proportions. In order to obtain a positive point estimate, make sure you subtract the lower value from the higher value when calculating the difference between the sample proportions. Provide your answer as a number between 0 and 1 rounded to 4 decimal places.
