r air travelers, one of the biggest complaints is of the waiting time between when the airplane kis away from the terminal until the flight takes off. This waiting time is known to have a right- ewed distribution with a mean of 10 minutes and a standard deviation of 7 minutes. Suppose O flights have been randomly sampled. Describe the sampling distribution of the mean waiting he between when the airplane taxis away from the terminal until the flight takes off for these O flights. A. Distribution is approximately normal with mean = 10 minutes and standard error = 0.8 minutes. B. Distribution is approximately normal with mean = 10 minutes and standard error = 8 minutes.

Question 5 For air travelers, one of the biggest complaints is of the waiting time between when the airplane taxis away from the terminal until the flight takes off. This waiting time is known to have a right- skewed distribution with a mean of 10 minutes and a standard deviation of 7 minutes. Suppose 100 flights have been randomly sampled. Describe the sampling distribution of the mean waiting time between when the airplane taxis away from the terminal until the flight takes off for these 100 flights. O A. Distribution is approximately normal with mean = 10 minutes and standard error = 0.8 minutes. O B. Distribution is approximately normal with mean = 10 minutes and standard error = 8 minutes. O C. Distribution is approximately normal with mean = 10 minutes and standard error = 7 minutes. D. Distribution is approximately normal with mean = 10 minutes and standard error = 0.7 minutes. Question 6 A sample of 25 circuits from a large normal population has a mean resistance of 3 ohms. We know from past testing that the population standard deviation is 1 ohm. Determine a 90% confidence interval for the true mean resistance of the population. What is the lower bound? 3.329 2.671 3.876 O 2.876
