My solution.

 

I didn't finish this challenge in 10 minutes by Tool version problem.

We must right click at tool and down the version 1.1 to 1.0.

I definitely wouldn't have made this round - couldn't get the correct answer until I remembered I needed to set the Tool Version for models to 1.0  (discovered this in Predictive Analytics course).   Once I did that it worked great.  I also used Model Compare to determine which tool to use (in addition to checking I output accuracy rating)  prior to scoring.

So, all three of these confirm that the Decision Tree model is the better predictor.

Looks like I did everything correctly,  but could not get the desired output.  Others have said the same... versioning issue.

I only got the right answer after I saw a tip from @JP_SDAK  to set the version to the predictive tools to 1.0.  It took me a while to figure out how to do that (right-click on each tool), but I don't know why that matters.  If anybody knows, I'd appreciate an explanation!

Thanks to others for pointing out the issue with the tool version (Right click and revert to 1.0 for both predictive tools).  I put the Logistic regression tool in a container and disabled it to avoid re-running each time.

I kept scratching my head why the Decision Tree model wasn't providing the correct answer until I figured it might be something in terms of changes in the Designer - reset the tools for 1.0 and voila.
