I have analyzed the image and can provide help with the following questions based on the stem-and-leaf plot shown:

### i. Determine the value of $ x $ and $ y $:
- $ x $ is the total number of data points in the set, which we calculate by counting all the leaves.
- $ y $ appears to refer to the stem unit, which is set as $ y = 10 $ in this case, because the leaf unit is given as 10.0.

### ii. What is the value of the highest yield?
- The highest yield corresponds to the highest stem-leaf value. We have stems 5, 11, 14, 3, and so on. The highest yield is from stem 5 and leaf 9, so the highest yield is $ 5.9 \times 10 = 59.0 $.

### iii. Find the modal yield:
- The modal yield is the most frequently occurring value. By looking at the leaves, the value "4" appears most frequently (five times in total), so the modal yield is $ 34.4 \times 10 = 344.0 $.

Do you want more details on the steps?

Here are some follow-up questions:
1. How do you calculate the median from a stem-and-leaf plot?
2. What is the significance of the stem unit in this display?
3. How would the mean yield be computed for this data set?
4. What is the range of this data set based on the plot?
5. How could this data be represented as a histogram instead?

**Tip:** In a stem-and-leaf plot, the number of digits in the stem and leaf helps determine the level of precision for the data values.

The following stem-and-leaf display of the dividend yields ($) for common stocks. Determine the value of x and y. What is the value of the highest value? Find the modal yield of this data set.

This problem focuses on interpreting a stem-and-leaf plot to find the total number of data points, modal yield, and the highest dividend yield. Perfect for students studying statistics in Grades 9-12.
