Option A is correct. 0.14 represents that if a student is a 10th grader, there is a 14% chance he or she has a job.
it is given that there is a column with 4 column and 3 rows.
<h3>what is a conditional relative frequency table?</h3>it is a special type of frequency table that shows relationships between two categories.
from the attached table it is clear that 0.14 is the probability of getting a job if a student is a 10th grader,
option B is incorrect, stating there is a 14% chance a student is a 10th grader if he/she has had a job since we do not know the number of students.
option C is also incorrect stating that 14% of the students surveyed are 10th graders who have a job since we do not know the total number of students.
option D is also incorrect because we do not know the number of students.
therefore, option A is correct. 0.14 represents that if a student is a 10th grader, there is a 14% chance he or she has a job.
