  1. Use the following data to answer the questions posed below.  This is data taken from a simple random sample of students in a class from a large  population.  The variables are defined as follows:

    • Student: Student ID.
    • Credits: # of credits earned
    • GPA: Current College GPA
    • Student’s Gender: Male/Female
    • Program:  Program of study
    • Final Exam: Students’ scores on final exam
    • SATM: Students’ SAT math scores

    The data are as follows

    student    credits      gpa        gender     program Final Exam   SATM     
    1 42 3.00 female Business 42.5 410

    15 37 2.32 female Arts & Sciences 47.5 440
    16 45 2.86 male Business 62.5 590

     

    Based on the cross tabulation, here is the joint probability table between events M and B, where M is the event that the individual is male, and B is the event that the individual is a business major.

             B           B^C                       
           M         0.31 0.06 0.44
           M^C 0.38 0.25 0.56
      0.69 0.31 1.00

     

    Based on this information, please compute each of the following, rounding your answers to two decimal points.

    1.  = P(M\B^C) =
    2.  = P(B^C\M) =
    3.  = P (M ∩ B^C) =
    4.  = P(B) = 
    5.  = P(B^C ∪ M^C) =
