1. Mr. Bueller gave his Algebra I class a test on statistics. After the test, he presented the following data to his
students regarding their test scores (scores are in percentages).
Lowest Score: 0
Mean: 74.5
First Quartile: 68
Standard Deviation: 18.5
Median: 77
Third Quartile: 85
Highest Score: 98
The lowest score was calculated as a zero because the student had been absent. Once the student returned to
school, she took the test. Unfortunately, she had been absent for most of the lessons and only scored a 53% which
is still the lowest score. How would replacing the 0% with a 53% affect the statistics? Place a check in the box that
describes the new value.
