A technology manufacturing company has recently switched to the production of isolinear processors. They can make 400 processors every hour, however the probability that a randomly chosen processor works properly is 50%. Determine the probability that, of the 400 processors made this hour, at most 208 are working properly.

The taxi and takeoff time for commercial jets is a random variable x with a mean of 8.7 minutes and a standard deviation of 3.5 minutes. Assume that the distribution of taxi and takeoff times is approximately 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 they take off one at a time on a given runway. (a) What is the probability that for 33 jets on a given runway, total taxi and takeoff time will be less than 320 minutes? (Round your answer to four decimal places.)(b) What is the probability that for 33 jets on a given runway, total taxi and takeoff time will be more than 275 minutes? (Round your answer to four decimal places.)(c) What is the probability that for 33 jets on a given runway, total taxi and takeoff time will be between 275 and 320 minutes? (Round your answer to four decimal places.)
Tutorial Exercise Given that z is a standard normal random variable, compute the following probabilities. (a) P(-1.95 sz s 0.46) (b) P(0.55 sz s 1.23) (c) P(-1.85 ≤zs -1.05) Step 1 (a) P(-1.95 sz≤ 0.46) For z to be a standard normal variable means that the random variable z follows a normal distribution with mean 0 and standard deviation 1. The normal distribution is a bell-shaped curve that is symmetric about the mean. The graph of a standard normal curve is below. -3 -2 -1 0 mean, " z -2.0 -1.9 1 This distribution is continuous, so probabilities will be for a range of values and represented by the area under the graph between the values. The desired probability is for the region between z = -1.95 and z = 0.46. Since z = -1.95 is to the left of z = 0.46, we can find this probability by subtracting the area under the curve to the left of z = -1.95 2 3 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.0228 0.0222 0.0217 0.0212 0.0207 0.0202 0.0197 0.0192 0.0188 0.0183 0.0287 0.0281…
