- A manufacturer knows that their items have a normally distributed length, with a mean of 8.9 inches, and standard deviation of 0.9 inches.If one item is chosen at random, what is the probability that it is less than 8.3 inches long?A manufacturer knows that their items have a normally distributed length, with a mean of 9.6 inches, and standard deviation of 2.8 inches. If one item is chosen at random, what is the probability that it is less than 14.2 inches long?An elevator has a placard stating that the maximum capacity is 4300 lb-28 passengers. So, 28 adult male passengers can have a mean weight of up to 4300/28 = 154 pounds. Assume that weights of males are normally distributed with a mean of 177 lb and a standard deviation of 36 lb. a. Find the probability that 1 randomly selected adult male has a weight greater than 154 lb. b. Find the ability that a sample of 28 randomly selected adult males has a mean weight greater than 154 lb. Question Viewer c. What about the safety of this elevator? you a. The probability that 1 randomly selected adult male has a weight greater than 154 lb is (Round to four decimal places as needed.)
- A manufacturer knows that their items have a normally distributed length, with a mean of 10.8 inches, and standard deviation of 0.6 inches.If one item is chosen at random, what is the probability that it is less than 11.3 inches long?An elevator has a placard stating that the maximum capacity is 2430 lb—15 passengers. So, 15 adult male passengers can have a mean weight of up to 2430/15=162 pounds. If the elevator is loaded with 15 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 162 lb. (Assume that weights of males are normally distributed with a mean of 171 lb and a standard deviation of 32 lb.) Does this elevator appear to be safe?It is known that the mean weight of students at cavendish university is 72 kg with a standard deviation of 3 kg. What would be the probability of finding individuals with weights between 74kg and 78 kg? ( Assume weight to be normally distributed).
