Add two more entries to the sample_training.zips collections
The lab task currently can be solved without paying attention to the difference between the $lt vs $lte and $gt vs $gte operators:
MongoDB Enterprise atlas-7ooiae-shard-0:PRIMARY> db.zips.find({"pop" : { $gte: 5000,$lte: 1000000}}).count()
11193
MongoDB Enterprise atlas-7ooiae-shard-0:PRIMARY> db.zips.find({"pop" : { $gt: 5000,$lt: 1000000}}).count()
11193
Adding two more documents (one with 5000 and the other one with 1000000 "pop" value) would draw attention to this difference
