Question

example 3
what do the highlighted cells best represent?
o a the number of people who are \2nd year students or work \2 jobs\
o b the number of people who are \2nd year students\.
o c the number of people who are \2nd year students and work \2 jobs\
o d the number of people who work \2 jobs\.

Explanation:

The highlighted cells (3, 11, 2) are in the row labeled "2nd Year Student". When we consider a contingency table like this, the values in a particular row (here, the "2nd Year Student" row) represent the distribution of the column - variable (number of jobs) among the members of that row - category. So, collectively, these values represent the number of people who are "2nd Year Students" across different job - holding situations. Option A is incorrect because the "OR" operation would involve more cells (including non - 2nd - year students with 2 jobs and 2nd - year students with other job numbers in a more complex calculation). Option C is incorrect as it refers to only one cell (the intersection of 2nd - year students and 2 jobs). Option D is incorrect as it would refer to the entire "2 Jobs" column.

Answer:

B. The number of people who are "2nd Year Students".
