Final answer:
The range of the math test scores, which is the difference between the highest and lowest score, is 34.
Step-by-step explanation:
To find the range of the scores on the math test, we subtract the lowest score from the highest score. The given scores are 77, 58, 64, 92, 81, and 65. Thus, the highest score is 92 and the lowest score is 58. The calculation will be 92 - 58 which equals 34. Therefore, the range of the scores on the math test is 34.
