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 14.5 in. and a standard deviation of 1 in. ​(a) Find the probability that if an individual man is randomly​ selected, his hip breadth will be greater than 16.1 in. ​(b) If a plane is filled with 110 randomly selected​ men, find the probability that these men have a mean hip breadth greater than 16.1 in.   ​(c) Which result should be considered for any changes in seat​ design: the result from part​ (a) or part​ (b)?

Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.
