How To Analyze A Case In a case study there is no right or wrong answer. The following suggestions will help you to analyze case studies more effectively: Read the case: The first step to a successful case solution is to read the case‚ carefully and with an eye for detail – more than once. Don’t rush through it. Look for the smallest of details. That is the only correct way to read intelligent conclusions. Look for case attachments and accompanying tables and numbers if available. Do not reach

and Case Problem 1. It is well established that the U.S. Court has the territorial jurisdiction to apply‚ the plaintiff will have to prove to the Court how the conduct of the defendant has an impact on the U.S. market and how their behavior was unlawful based on the Sherman Act. If the plaintiff will be able to prove that the Slobovian’s cartel rejecting the purchasing of the goom mine has a negative effect on the U.S. customers‚ then the Sherman Act can be applied.

sample or a population is computed by adding all of the observations and dividing by the number of observations. Returning to the example of the five women‚ the mean weight would equal (100 + 100 + 130 + 140 + 150)/5 = 620/5 = 124 pounds. In the general case‚ the mean can be calculated‚ using one of the following equations: Population mean = μ = ΣX / N OR Sample mean = x = Σx / n where ΣX is the sum of all the population observations‚ N is the number of population observations‚ Σx is the sum of

an array of simple and conditional probabilities. For example: Suppose there is a certain disease randomly found in one-half of one percent (.005) of the general population. A certain clinical blood test is 99 percent (.99) effective in detecting the presence of this disease; that is‚ it will yield an accurate positive result in 99 percent of the cases where the disease is actually present. But it also yields false-positive results in 5 percent (.05) of the cases where the disease is not present.
