An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 181 Ib. The new population of pilots has normally distributed weights with a mean of 136 Ib and a standard deviation of 26.1 lb. Click here to view page 1 of the standard normal distribution. Click here to view page 2 of the standard normal distribution, a. If a pilot is randomly selected, find the probability that his weight is between 130 Ib and 181 Ib. The probability is approximately 0.5486. (Round to four decimal places as needed.) b. If 38 different pilots are randomly selected, find the probability that their mean weight is between 130 Ib and 181 Ib. The probability is approximately (Round to four decimal places as needed.)

Suppose that the walking step lengths of adults are normally distributed with a mean of 2.4 feet and a standard deviation of 0.3 feet. A sample of 34 step lengths is taken. Find the probability that the mean of the sample taken is more than 2.5 feet. Your answer should be from the cumulative normal distribution table.
An engineer is going to redesign an ejection seat for the airplane. The seat was designed for pilots weighing between 150 and 191 pounds. The new population of pilots has normally distributed weights with a mean of 158 pounds and a standard deviation or 31.1 pounds. a. If a pilot is randomly selected, find the probability that his weight is between 150 lb and 191 lb. b. If 38 pilots are randomly selected, find the probability that their mean weight is between 150 lb and 191 lb. what is the approximate probability? c.

Although controversial, some human resources departments administer standard IQ tests to potential employees. The Stanford-Binet test scores are well modelled by a Normal model with mean 100 and standard deviation 17 If the applicant pool is well modelled by this distribution, a randomly selected applicant would have what probability of scoring in the following regions? Use the 68-95-99.7 Rule to approximate the probabilities rather than using technology to find the values more precisely. Complete parts a through d. Question content area bottom Part 1 a) What is the probability of scoring 100 or below? (Type an integer or a decimal.) Part 2 b) What is the probability of scoring 117 or above? (Type an integer or a decimal.) Part 3 c) What is the probability of scoring between 49 and 151? d) What is the probability of scoring above 134?
