Transcribed Image Text:**Efficiency Ratio and Temperature Data for Steel Immersion in Phosphating Tank**
*Overview:*
The efficiency ratio for steel immersed in a phosphating tank is calculated as the weight of the phosphate coating divided by the metal loss (both in mg/ft²). Data below represents the temperature of the tank along with the corresponding efficiency ratios.
**Data Table:**
| Ratio | Temp | Ratio | Temp |
|-------|------|--------|------|
| 2.15 | 181 | 1.07 | 180 |
| 0.85 | 180 | 1.08 | 180 |
| 1.43 | 182 | 0.98 | 180 |
| 0.90 | 181 | 1.24 | 189 |
| 2.60 | 180 | 1.14 | 174 |
| 1.49 | 179 | 1.57 | 175 |
| 2.52 | 177 | 1.45 | 180 |
| 3.00 | 175 | 1.60 | 185 |
| 1.87 | 186 | 1.61 | 186 |
| 3.08 | 182 | 2.13 | 180 |
**Stem-and-Leaf Display of Temperature:**
(a) Construct a stem-and-leaf display of temperature by splitting the stems. Place leaves 0 to 1 on the first stem, leaves 2 to 3 on the second stem, etc. Enter numbers from smallest to largest. Enter NONE for stems with no values.
- **Stem | Leaf**
- 17 |
- 18 | 1 1 2 0 2 2 0 0 5
- 19 |
**Instructions and Observations:**
- The distribution of temperatures are mostly around the 180°F mark.
- The efficiency ratio shows variance, with some data points being significantly higher.
- To create a stem-and-leaf plot manually, truncate the hundreds digit from the temperatures, and then organize leaves on the stems systematically.
- Focus on interpreting both efficiency ratio changes and temperature effects from the data for steel processing optimizations.
![The image contains instructions and a table for creating a stem-and-leaf plot to display efficiency ratio data. Here is the transcription of the text and details of the table:

### Instructions:
**Comment on interesting features.**
- **The distribution is [Select] and the variation is [Select].**
**Construct a stem-and-leaf display of efficiency ratio:**
(Truncate the hundredths digit and split the stems, placing leaves 0 to 1 on the first stem, leaves 2 to 3 on the second stem, etc. Enter numbers from smallest to largest separated by spaces. Enter NONE for stems with no values.)

- The table consists of two columns labeled "Stem" and "Leaf"
- Each "Stem" is a whole number, and "Leaf" is meant to display decimal digits arranged in ascending order for each stem
- The instructions are aimed at ordering numbers in a specific format, dividing digits between stems
This setup is typically used in educational settings to teach students how to summarize data visually through a stem-and-leaf plot, often used in statistics to assess the distribution and variation of a dataset.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F379782e3-36e2-4b06-9a33-e2601af30423%2F8d09ca40-9d8d-4e2c-89e8-56c3e4c33898%2F8yqzkxp_processed.jpeg&w=3840&q=75)
