Because statistical software plays such an important role in modern statistical applications,many studies have encouraged the use of technology in statistics courses.The Guidelines for the Assessment and Instruction in Statistics Education (GAISE)(Aliaga et al. ,2005)project was funded by the American Statistical Association to examine needs for college level statistics courses.One of the six recommendations from GAISE is the use of technology for developing conceptual understanding and analyzing data.A survey was sent to students at 100 different universities across the United States to access the relationship between ease of learning the statistical software program SAS and a student's currently level of SAS proficiency.The results of the survey are published in Jackson et al. ,2011,in the International Mathematical Forum journal and are shown below. Table 1.Two-way table for ease of learning SAS and SAS proficiency level. What is the expected cell count for students who find SAS very easy to learn and who are not proficient?
A)5.7
B)1
C)179.2
D)None of the above

To find the expected cell count for students who find SAS very easy to learn and who are not proficient, we need to multiply the row and column totals for that cell and divide by the total sample size. So, for the cell of interest, we have:
Expected cell count = [(166+91)/479]*[(75+62)/479]*479 = 5.7
Therefore, the best choice is A.
