To calculate the median with the 8 replaced by a 10, we first need to rearrange the scores in each class section from least to greatest:
Class 1: 6, 7, 7, 9, 9, 10, 10, 10
Class 2: 5, 6, 8, 9, 9, 10, 10, 10
Class 3: 6, 7, 7, 8, 9, 9, 10, 10
Now, we need to find the median in each class section:
Class 1: (9+9)/2 = 9
Class 2: (9+9)/2 = 9
Class 3: (8+9)/2 = 8.5
Finally, we calculate the overall median by finding the median of the three class medians:
Median: (8.5+9+9)/3 = 8.5
Therefore, the median score when the 8 is replaced with a 10 is 8.5.
Class 1: 6, 7, 7, 9, 9, 10, 10, 10
Class 2: 5, 6, 8, 9, 9, 10, 10, 10
Class 3: 6, 7, 7, 8, 9, 9, 10, 10
Now, we need to find the median in each class section:
Class 1: (9+9)/2 = 9
Class 2: (9+9)/2 = 9
Class 3: (8+9)/2 = 8.5
Finally, we calculate the overall median by finding the median of the three class medians:
Median: (8.5+9+9)/3 = 8.5
Therefore, the median score when the 8 is replaced with a 10 is 8.5.
