Answer

Answer:

D. 0.40

Explanation:

Step1: Recall conditional - relative frequency concept

In a conditional relative - frequency table by column, the sum of the conditional relative frequencies in each column is 1. To find the value of (X), we add the conditional relative frequencies in the "English Only" row for the two grade categories.

Step2: Perform the addition

(X=0.12 + 0.28) (X = 0.40)
