How many shipments had at least 25 broken tiles but less than 67 broken tiles?

Answer 1

To find the answer, we need to count the number of shipments with broken tiles between 25 and 66 (inclusive).

Looking at the stem-and-leaf plot, we can see that:

- There are no shipments with exactly 25, 26, 27, or 28 broken tiles.
- There is one shipment with exactly 29 broken tiles (stem = 2, leaf = 9).
- There are four shipments with exactly 30 broken tiles (stem = 3, leaves = blank).
- There are no shipments with exactly 31, 32, or 33 broken tiles.
- There is one shipment with exactly 34 broken tiles (stem = 3, leaf = 4).
- There are two shipments with exactly 35 broken tiles (stem = 3, leaves = 5 and 5).
- There are no shipments with exactly 36 or 37 broken tiles.
- There is one shipment with exactly 38 broken tiles (stem = 3, leaf = 8).
- There are three shipments with exactly 39 broken tiles (stem = 3, leaves = 9 9 9).
- There are no shipments with exactly 40 or 41 broken tiles.
- There is one shipment with exactly 42 broken tiles (stem = 4, leaf = 2).
- There are no shipments with exactly 43 or 44 broken tiles.
- There are two shipments with exactly 45 broken tiles (stem = 4, leaves = 5 9).
- There are no shipments with exactly 46, 47, 48, or 49 broken tiles.
- There is one shipment with exactly 50 broken tiles (stem = 5, leaf = 0).
- There are no shipments with exactly 51 or 52 broken tiles.
- There are two shipments with exactly 53 broken tiles (stem = 5, leaves = 3 9).
- There are no shipments with exactly 54, 55, or 56 broken tiles.
- There is one shipment with exactly 57 broken tiles (stem = 5, leaf = 7).
- There are no shipments with exactly 58 or 59 broken tiles.
- There are three shipments with exactly 60 broken tiles (stem = 6, leaves = 9 9 9).
- There are no shipments with exactly 61, 62, 63, or 64 broken tiles.
- There is one shipment with exactly 65 broken tiles (stem = 6, leaf = 5).
- There are no shipments with exactly 66 broken tiles.

Adding up all the counts, we get a total of 20 shipments with broken tiles between 25 and 66 (inclusive). So the answer is 20.

Answer 3

I apologize for the error in my previous response. Upon reviewing the stem-and-leaf plot again, I see that there are indeed seven shipments with broken tiles between 25 and 66 (inclusive). I apologize for any confusion caused by my mistake and thank you for bringing it to my attention so that I could correct it.
