Question

1. The first 3 moments of a distribution about the value 7, calculated from a set of 9 observations are 0.2, 19.4 and -41.0. Find the measures of central tendency and dispersion and also the third moment about origin.

Definition Definition Characteristic of data to concentrate at certain values, usually in the center of the distirbution. The central tendency of the data is measured by descriptive statistics like mean, median, and mode, which are known as measures of central tendency. Depending upon the type of data under study, some measures of central tendency become more appropriate to use than others.

Jack's clothing sells on average, 25 shirts per week, sometimes a little more, sometimes a little less but typically a deviation of about 3. The cost per jacket is $65. Because Jack's is located in a sketchy part of town their insurance on inventory is 33% on all goods. The good news is free shipping to customers although UPS charges Jack's $8.50 for every delivery. It takes 2 weeks from the time jackets are ordered until they are received. Jack's supplier has said they only ship by pallet, and each pallet contains 75 jackets. If the reorder point is 50 what is the average flow time?

David and Patrick are playing baseball for the Cafe Tropical team. Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a standard deviation of 50 feet. If X = distance in feet for a fly ball, then X ~ N ( , ) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled less than 220 feet?
