Assume that the population of interest is all 97.494 Penn State students, unless otherwise specified. Use the following notation: U = Undergraduate W = World Campus Data from http://budget.psu.edu/factbook/StudentDynamic/UGGREnrollSummaryByAdvisor.aspx?YearCode=2015Enr&FBPlusIndc=N A. Compute P(U) Answer: Undergraduates = 83436/97494 B. Compute P(W) Answer: World Campus Students =7242/97494 C. Compute P(UC) D. Compute P (U W) E. Compute P (U W) F. If you were to randomly select one Penn State student from this population, what is the probability that the student is a University Park undergraduate student? G. Given that a randomly selected student is an undergraduate student, what is the probability that they are a World Campus student? H. Given that a randomly selected student is not an undergraduate student, what is the probability that they are a World Campus student? I. Using the formulas from the online notes, check if the events U and W are independent. J. Are U and W disjoint events? Why or why not? 2. [44 points] Open the dataset Fall16StData.MTW in Minitab Express. Unless otherwise noted, assume that the population of interest all of the students who responded to this survey. A. Make a contingency table for the dog and cat variables. Copy + paste it here. B. Is a contingency table an appropriate way to display data concerning dog and cat ownership? Why or why not? C. Compute P (Dog) D. Compute P (Dog Cat) E. Compute P (Dog Cat) F. Compute P (Cat Dog) G. Compute P (Dog Cat) H. Make a contingency table for the biological sex and alcohol preference variables. Copy + paste it here. I. Given that a randomly selected student is a male, what is the probability that he prefers beer? J. Given that a randomly selected student is a female, what is the probability that she prefers beer? K. Compute P (FemaleC wine). 3. [16 points] At one university, 88% of students speak English, 60% of students speak French, and 50% of students speak both English and French. A. Are speaking English and speaking French independent events? Show the calculations that you used to determine this. B. What is the probability that a randomly selected student speaks either English or French? C. What is the probability that a randomly selected student speaks neither English nor French? d. Given that a student does not speak French, what is the probability that he or she speaks English
