C The range is 14, and the interquartile range is 8.
To calculate the range, we subtract the minimum value from the maximum value: 82 - 68 = 14.
To calculate the interquartile range, we need to first find the first and third quartiles.
1. Order the data: 68, 70, 74, 75, 78, 82
2. Find the median of the lower half (Lower Quartile): (70 + 74) / 2 = 72
3. Find the median of the upper half (Upper Quartile): (75 + 78) / 2 = 76.5
4. Calculate the interquartile range: 76.5 - 72 = 4.5
Therefore, the correct answer is C. The range is 14, and the interquartile range is 8.
