Question

Suppose that an airline uses a seat width of 16.1 in. Assume men have hip breadths that are normally distributed with a mean of 14.3 in. and a standard deviation of 1 in.

Complete a-c

round 4 decimal places as needed

Suppose that an airline uses a seat width of 16.1 in. Assume men have hip breadths that are normally distributed with a mean of 14.3 in. and a standard deviation of 1 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 16.1 in.
The probability is
(Round to four decimal places as needed.)
(b) If a plane is filled with 120 randomly selected men, find the probability that these men have a mean hip breadth greater than 16.1 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
should be considered because

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
