To determine the day on which the new machine made a positive impact on production, we'll examine the given data closely. The usual production range is between 20 and 22 pot stickers per hour. The production data for the seven days are as follows:

- Day 1: 20 pot stickers per hour
- Day 2: 22 pot stickers per hour
- Day 3: 21 pot stickers per hour
- Day 4: 10 pot stickers per hour
- Day 5: 15 pot stickers per hour
- Day 6: 50 pot stickers per hour
- Day 7: 55 pot stickers per hour

We need to identify the first day when the production exceeds the usual upper limit of 22 pot stickers per hour. Analyzing the data day by day:

1. Day 1: 20 pot stickers per hour (within the usual range)
2. Day 2: 22 pot stickers per hour (within the usual range)
3. Day 3: 21 pot stickers per hour (within the usual range)
4. Day 4: 10 pot stickers per hour (below the usual range)
5. Day 5: 15 pot stickers per hour (below the usual range)
6. Day 6: 50 pot stickers per hour (exceeds the usual range)
7. Day 7: 55 pot stickers per hour (exceeds the usual range)

The first day on which production exceeds 22 pot stickers per hour is Day 6.

Thus, the day on which the machine makes a positive impact on production is:

Day 6
