Assessing the Distribution of Three VariablesIn this assignment, you will characterize three variables in the ISLR College data set to determine whether the normal approximation is appropriate for that variable. You will need to load the ISLR package as well as MASS and stats. 1.Assess the distribution of the three variables (Accept, Grad.Rate, and PhD) and determine if the normal approximation is appropriate for their analysis. a.Plot a his...

Question 1: Rolling a Die1.What is the probability of rolling a four with a six sided die?  What is the probability that a person can roll a four 3 times in a row? (assume that rolling the die each time does not affect the outcome of the next roll) 2.Population A and Population B both have a mean height of 70.0 inches with an SD of 6.0.  A random sample of 50 people is picked from population A, and random sample of 20 people is sele...

Part 1: Correlation and Linear RegressionThere is a population of workers in this country who are employed but who do not earn enough in wages to securely cover the cost of their family’s basic needs. Although the numbers vary by state or district, these individuals and their families are similar in that they cross racial, cultural, and local boundaries. They are considered the nation’s “Working Poor.” This common grade...

Value Chain in Detail for Home Bed Mattress IndustryOne of the most cumbersome items to buy is a bed mattress to sleep on. It is difficult to know how the product will perform before purchase and the large size makes mattresses difficult to transport. Several firms have begun to explore ways to disrupt this industry but arguably there is a long way to go before a truly viable business model will emerge. Two references are provided concerning...
