HW 12, task 2 and task 10 contains the same "correlation" function, yet defined differently

This results in error in the final auto grading function. I suggest change the task 2 "correlation" to a different name( such as "correlation coefficient" )with a change on its auto grading, since it involves less of subsequent usage than task 10.

@shihwachang, good catch! I'll fix that now by using correlation_coefficient as the name of the function you create in Task 02. Additionally, I'll remove the redundant task that asks you to re-create the standard_units function in Part 1 of Task 10.

Steps

• [x] Update the function name from correlation to correlation_coefficient in Task 02. (This impacts Task 05 since it is assumed that students will need to use the function from Task 02.)
• [x] Update the instructions for Task 10 to prevent students from recreating the standard_units function.
• [x] Update the instructions for Task 10 to have students create a new correlation function called correlation.
• [x] Provide a note in Task 10 to use the standard_units function from Task 01 to create correlation.

The changes were made, but I'll leave this issue open until the assignment deadline for reference.
