A national air traffic control system handled an average of 47,368 flights during 28 randomly selected days in a recent year. The standard deviation for this sample is 6,415 flights per day. Completeparts a through c below.The 99% confidence interval to estimate the average number of flights per day handled by the system is from a lower limit of to an upper limit of.(Round to the nearest whole numbers.)b. Suppose an airline company claimed that the national air traffic control system handles an average of 50,000 flights per day. Do the results from this sample validate the airline company's claim?A. Since the 99% confidence interval does not contain 50,000, it cannot be said with 99% confidence that the sample validates the airline company's claim.B. Since the 99% confidence interval contains 50,000, it cannot be said with 99% confidence that the sample validates the airline company's claim.O C. Since the 99% confidence interval contains 50,000, it can be said with 99% confidence that the sample validates the airline company's claim.D. Since the 99% confidence interval does not contain 50,000, it can be said with 99% confidence that the sample validates the airline company's claim.c. What assumptions need to be made about this population?A. Since the sample size is not greater than or equal to 30, one needs to assume that the population follows the Student's t-distribution.B. Since the sample size is not greater than or equal to 30, one needs to assume that the population distribution is skewed to one side.C. Since the sample size is not greater than or equal to 30, one needs to assume that the population follows the normal probability distribution.D. Since the sample size is not greater than or equal to 30, one needs to assume that the population distribution is not very skewed to one side.

Given that the sample size is n = 28 Sample mean = 47368 Sample SD = 6415 The critical value of t at…

A district official intends to use the mean of a random sample of 150 sixth graders from a very large school district to estimate the mean score that all the sixth graders in the district would get if they took a certain arithmetic achievement test. If, based on experience, the official knows that = 9.4 for such data, suppose that the district official takes her sample and gets = 61.8. Use all the given information to construct a 99% confidence interval for the mean score of all the sixth graders in the district.

Suppose a researcher takes a random sample of 1,000 students from a university and creates a 95% confidence interval for the true proportion of left handed students at the university. Which of the following is true about this interval when compared with a 95% confidence interval based on a random sample of 600 students from the same university? a. The interval based on a sample of 600 students will be wider than the interval based on a sample of 1,000 students. b. The lower and upper endpoints of the 95% CI based on 600 students will both be larger than the corresponding lower and upper endpoints of the 95% CI based on 1,000 students. c. 95% CIs based in samples of 1,000 students are more likely to include the true population proportion than 95% CIs based on samples of 600 students. d.
