Suppose that an airline uses a seat width of 16.7 in. Assume men have hip breadths that are normally distributed with a mean of 14.7 in. and a standard deviation of 0.9 in. Complete parts (a) through (c) below. (a) Find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.7 in. The probability is. (Round to four decimal places as needed.) (b) If a plane is filled with 126 randomly selected men, find the probability that these men have a mean hip breadth greater than 16.7 in. The probability is. (Round to four decimal places as needed.) (c) Which result should be considered for any changes in seat design: the result from part (a) or part (b)? The result from V should be considered because
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
How do you solve this?
![Suppose that an airline uses a seat width of 16.7 inches. Assume men have hip breadths that are normally distributed with a mean of 14.7 inches and a standard deviation of 0.9 inches. Complete parts (a) through (c) below.
(a) Find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.7 inches.
The probability is [___].
(Round to four decimal places as needed.)
(b) If a plane is filled with 126 randomly selected men, find the probability that these men have a mean hip breadth greater than 16.7 inches.
The probability is [___].
(Round to four decimal places as needed.)
(c) Which result should be considered for any changes in seat design: the result from part (a) or part (b)?
The result from [___] should be considered because [___].](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fffe6432d-dce4-4c70-a711-bda2e82cb940%2Fc79540ea-e1c2-421e-ac3d-06880bcd0bdd%2F28t3mlj_processed.jpeg&w=3840&q=75)
