Range:9
Median:5
Mode:5
To find the range of the data in a stem-and-leaf plot, you need to identify the smallest and largest values. In this case, the smallest value is 54 and the largest value is 96. The range is calculated by subtracting the smallest value from the largest value:
Range = Largest Value - Smallest Value
Range = 96 - 54
Range = 42
Therefore, the range of the data is 42.
To find the median of the data, you need to arrange the values in ascending order and then determine the middle value. In this case, the values in ascending order are: 54, 55, 60, 69, 72, 73, 74, 75, 76, 81, 82, 88, 89, 95, 96.
Since there are 15 values, the median is the 8th value (middle value) when arranged in ascending order. So the median is 75.
To find the mode of the data, you need to identify the value(s) that appears most frequently. In this case, the number 5 appears most frequently with a frequency of 3. Therefore, the mode of the data is 5.
So the answers to your questions are:
A) The range of the data is 42.
B) The median of the data is 75.
C) The mode of the data is 5.
