Final answer:

The exact percentage of students who scored between 50 and 70 points on an exam cannot be calculated without additional data. Percentiles can provide insights into the distribution of scores, but they are not sufficient to determine the percentage in a specific score range.

Step-by-step explanation:

The question does not provide sufficient data to calculate the exact percentage of students who scored between 50 and 70 points on an exam. In order to accurately determine what percentage of students scored within this range, we would need specific data on the number of students who achieved scores within this interval. However, based on the provided information, we can discuss percentiles and interpret given values in a general context.

For instance, having the information that the 90th percentile is 69.4 implies that 90 percent of the test scores fall at or below 69.4 points. Using percentiles helps describe the distribution of scores on an exam and can give us some understanding of where a particular score stands in relation to others.

When discussing percentiles in the context of a test, it is important to remember that a higher percentile indicates a higher ranking among test-takers. Thus, a student in the 70th percentile did better than 70 percent of the other students. Similarly, in the provided example, an 80th percentile score of 49 points on a 60-point assignment suggests that the student scored higher than 80 percent of their peers.
