Answer :
The range of a set of numbers is the difference between the largest and smallest numbers in the set.
Given the data set: 67, 78, 78, 80, 81, 82, 86
The smallest number is 67 and the largest number is 86.
To find the range, subtract the smallest number from the largest number:
\[ \text{Range} = \text{Largest number} - \text{Smallest number} \]
\[ \text{Range} = 86 - 67 \]
\[ \text{Range} = 19 \]
So, the range of the data set is 19.
Given the data set: 67, 78, 78, 80, 81, 82, 86
The smallest number is 67 and the largest number is 86.
To find the range, subtract the smallest number from the largest number:
\[ \text{Range} = \text{Largest number} - \text{Smallest number} \]
\[ \text{Range} = 86 - 67 \]
\[ \text{Range} = 19 \]
So, the range of the data set is 19.
19.
86 - 67 - 19. (Smallest number subtracted from the highest number).
