7. Mrs. Smith's class took a test on solving quadratics. After she graded the tests, she calculated the following statistics for them. If she realized she made a mistake on the lowest score and the student's
grade increased by 5 points, pick how this will affect the statistics:
Below is what she calculated:
Lowest Score: 53+5=58
Median: 75
Highest Score: 95
First Quartile: 63
Third Quartile: 82
Mean: 74
Standard Deviation: 13
