The taxi and takeoff time for commercial jets is a random variable x with a mean of 8.2 minutes and a standard deviation of 3.4 minut normal. You may assume that the jets are lined up on a runway so that one taxies and takes off immediately after the other, and that t in USE SALT (a) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be less than 320 minutes? (Round x 0 (b) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be more than 275 minutes? (Rounc (C) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be between 275 and 320 minutes?

B. two events are dependent if the occurrence of one event changes to occurrence of the second event. true or false

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
