On a certain standardized testThe mean is 49The standard deviation is 12Scores are whole numbersNorman scored 40Find numbers a, b, and c such that approximately LaTeX: 100\cdot\left(\Phi^c\left(a\right)- \Phi^c\left(b\right)\right)100 ⋅ ( Φ c ( a ) − Φ c ( b ) ) percent of people who took the test scored exactly the same as Norman. Make a continuity correction. What is sin(a) - sin(b) + sin(c)? Make sure your calculator is set to use radians, not degrees. That is standard in math.
