Solution:
If the mean score for the juniors were known, which of the following could be calculated from the information given?
Ⅰ.The range of the scores for the seniors- We cannot find range for seniors and the total can be found in several ways i.e it could be 74-84 or 80-90- OUT
Ⅱ.The median score for the juniors- We also cannot find the median. If all the value are different then the median will be different and if it consists of one number eg. 6 students have a score of 76 then the median will be 76- OUT
Ⅲ.The mean score for the seniors- True, we can find the mean of the senior as we know the total score and total number of students and we can subtract the total of total students by the total score of juniors.- Correct
Hope this helps!
