To find: The pair of variables that are independent.
Answer to Problem T6.4SPT
The option (d) is showing the independent variables.
Explanation of Solution
Given:
The variables that are independent are required to find out.
Independent variables are those variables that are not independent on any another variable. Here, the pair of random variables “Average amount of homework done by student per night” and “height of the student” are independent variable. Because the height of the student cannot be predicted by the average amount of homework done by student per night. So, these two variables are independent.
Hence, the correct option is (e).
