On a certain standardized test . The mean is 49 . The standard deviation is 14 . Scores are whole numbers . Norman scored 69 Find numbers a, b, and c such that approximately 100 . (P (a) - d' (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. 0.8516 P(x - 0.5
