Final answer:
To find the relative frequency of scores of 67-74, divide the number of scores in that range by the total number of scores. The same process applies to finding the relative frequency of scores of 91-106.
Step-by-step explanation:
To find the relative frequency of scores of 67-74, we need to count the number of scores in that range and divide by the total number of scores. Let's say there are 10 scores in that range and a total of 50 scores. The relative frequency would be 10/50 = 0.2.
To find the relative frequency of scores of 91-106, we follow the same process. Let's say there are 5 scores in that range. The relative frequency would be 5/50 = 0.1.
Thus, the relative frequency of scores of 67-74 is 0.2 and the relative frequency of scores of 91-106 is 0.1.
