T or F: More than half of the scores Are 85% or above. Gloria has taken 5 tests: None are the same score The median is 83% The mean is 85% T or F: More than half of the scores Are 85% or above. T or F: More than half odd the scores Are 83% or above. T or F: All scores are above 83%. T or F: There are 2 or more scores at 85%. T or F: She scored an 85% on one test.

Gloria has taken 5 tests: None are the same score The median is 83% The mean is 85% If you scored a 98% on the next test, what will happen to your mean? If you scored an 80% on the next test, what will happen to your mean? If you scored an 85% on the next test, what will happen to your mean?
