You may need to use the appropriate appendix table or technology to answer this question. Amazon.com is testing the use of drones to deliver packages for same-day delivery. In order to quote narrow time windows, the variability in delivery times must be sufficiently small. Consider a sample of 23 drone deliveries with a sample variance of s2 = 0.36. (Round your answers to two decimal places.) (a) Construct a 90% confidence interval estimate of the population variance for the drone delivery time. Correct: Your answer is correct. to Incorrect: Your answer is incorrect. (b) Construct a 90% confidence interval estimate of the population standard deviation. Correct: Your answer is correct. to Correct: Your answer is correct.
