Answer
Explanation:
Step1: Recall the concept of column - conditional relative frequency
In a conditional relative frequency table by column, the sum of the conditional relative frequencies in each row is the total for that row.
Step2: Calculate the value of X
For the "English Only" row, we add the conditional relative frequencies for the two columns. So, $X=0.12 + 0.28$. $X = 0.40$
Answer:
0.40
