Answer:
Option Y is correct.
Explanation:
We are given the table representing the relation between new students and returning students for difference classes.
It is required to form the relative frequency table for the given situation.
So, relative frequency table is obtained by dividing the valued by the total number of values in the data set.
Thus, we will get the relative frequency table by dividing the given table values by 500.
Hence, we will get the following table,
New Students Returning Students Total
10th 0.01 0.34 0.35
11th 0.006 0.324 0.33
12th 0.004 0.316 0.32
Total 0.02 0.98 1
Thus, option Y is correct.
