Descriptive Statistics and Probability Exercises
A survey conducted by the Northwestern University Lindquist-Endicot Report asked 320 companies about the procedures they use in hiring. Only 54 %% of the responding
companies review the applicant's college transcript as part of the hiring process, and only 44% consider faculty references. Assume that these percentages are true for the
population of the companies in the United States and that 35% of all companies use both the applicant's college transcript and faculty references.
a. What is the probability that a randomly selected company uses either faculty references or college transcript as part of the hiring process?
b. What is the probability that a randomly selected company uses either raculty references or college transcript but not both as part of the hiring process?
c. What is the probability that a randomly selected company uses neither faculty references nor college transcript as part of the hiring process?
d. Construct a joint probability table for this problem and indicate the locations of your answers for parts (a), (b), and (c) on the table.View Full Posting Details
