4) We can use the output of table() with barplot() to view the frequency of levels in a factor. Extending our discussion of rolling die, we can use this to view the likelihood of rolling any particular value on one die using barplot(table(sample(x=1:6,size=1000,replace=TRUE))). How does this change if we add the rolls of 2 dice together? (Hint: recall that vectors are added in an element-wise fashion, and that sample() returns a vector). Extra What happens if the two dice have different numbers of sides?

Probabilities: Sampling Means Now that we know when we can use the normal distribution, we can use the Empirical Rule and the Normal Table (opens in new window) to find the probabilities. Example 1 Recall our earlier scenario: The Federal Pell Grant Program provides need-based grants to low-income undergraduate and certain post-baccalaureate students to promote access to post-secondary education. According to the National Post-secondary Student Aid Study conducted by the U.S. Department of Education in 2008, the average Pell grant...
Assignment Specifications We are going to use the Monte Carlo Method to determine the probability of scoring outcomes of a single turn in a game called Pig. Your Task For this assignment you will simulate a given number of hold?at?N turns of a game called Pig, and report the estimated probabilities of the possible scoring outcomes. You are NOT implementing the game of Pig, only a single turn of this game. The value of N will be acquired via user...

How can we assess whether a project is a success or a
failure?
This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects. Bombardier and Its Environment Joseph-Armand Bombardier was 15 years old when he built his first snowmobile...
Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
