part d+e+f+g+h Salma who took the Tawjihi exam scored 94.6 in mathematics and 93.7 in physics. The meanscore for mathematics for all test takers was 86.1 with a standard deviation of 4.4, and themean score for physics was 81.7 with a standard deviation of 5.33. Suppose that bothdistributions are nearly normal.Write down the shorthand (abbreviated formula) for these two normal distributions, e.g., X- N(H, o?).а.b. What is Salma's Z-score in mathematics? And in physics?What do these Z-scores tell you?С.d. Relative to others, which subject did she do better on?e. Find her percentile scores for the two exams. (use R-code)f.What percent of the test takers did better than her in mathematics? And in physics?g. Explain why simply comparing raw scores from the two sections could lead to an incorrectconclusion as to which subject a student did better on.h. If the distributions of the scores on these exams are not nearly normal, would your answersto parts (b) - (f) change? Explain your reasoning.
