You have a homework due today: pp. 289 & 290
Your exams:
Max: 63.5
Mean: 41.3 out of 70
Median: 42.5
Standard Deviation: 11.4
Curve: I'm going to map 42 to 75, and map the max score to a 95. I'll do this in a linear fashion, so that
(42,75) and (63.5,95)
are points on the line. What's the equation of the curve?
Use point-slope:
