Can the ti nspire cx cas calculate X-bar, Std Dev & Mean solved with One Variable with 4 columns of data?

Hello All,

I am trying to solve this problem by using Lists, Statistics, One Variable as it saves a lot of time compared to other methods.

My problem is that I don't quite get the all the answers correct when I calculate it with this method.

1.) Are we able to solve the problem with this method while having multiple columns of data like (4) from the problem shown below?

 

I have only seen this method solved where the users only have 2 columns of data. I have searched the internet to find an example of four columns of data being calculated and have not been successful. Any help is much appreciated.

Here's a Youtube Video of a user calculation it with only 2 columns:
