### Minimum value in the last class:
### Range:
### Number of values greater than 60:
Explanation
## Step 1: Count the Data Values### Count all the leaves in the stem-and-leaf plot. Each leaf represents a data value. There are 5 leaves for stem 5, 2 leaves for stem 6, 7 leaves for stem 7, and 4 leaves for stem 8. Therefore, the total number of data values is
.## Step 2: Find Minimum Value in the Last Class### The last class is represented by the stem 8. The minimum value in this class is formed by combining the stem 8 with the smallest leaf in that row, which is 1. So, the minimum value in the last class is 81.## Step 3: Calculate the Range### The minimum value in the entire dataset is formed by the smallest stem (5) and the smallest leaf in that row (2), which is 52. The maximum value is formed by the largest stem (8) and the largest leaf in that row (9), which is 89. The range is the difference between the maximum and minimum values:
.## Step 4: Count Values Greater than 60### Identify all values greater than 60. All values with stems 7 and 8 are greater than 60. For stem 6, only leaves greater than 0 contribute. There are 7 values for stem 7 and 4 values for stem 8. For stem 6, there are 2 leaves greater than 0. So, there are
values greater than 60.
