Incorrect aggregrate function for averages for 5 minute intervals

[adoersam]

in your aggregrate functions for the daily activity per 5 minute interval you used "sum" instead of "mean". That's why your most active 5 minute interval has more than 10000 steps, that's about 36 steps / second... :-)

Still gave you full points though.

Thanks. I had multiple versions of that code before I made the final
cut, but missed that detail.
