Math 302 Distribution) Exercises Set 8 (Normal December 2021 2- Suppose that the GPA of students at Tulane is normally distributed with mean 3.56 and standard devotion 0.3. What is the minimum GPA that would put a student in the top 10% of Tulane students? Let X equal the IQ of a randomly selected American. Assume X~ N(104, 182). What is the probability ?that a randomly selected American ?has an IQ below 75.1 O 0.0537 0.8888 0.8351 0.768 Let X equal the IQ of a randomly selected American. Assume X~ N(104,182). What is the probability ?that a randomly selected American ?has an IQ between 92 and 126.2 0.3085 0.8362 0.58 0.46 If the temperature in a city follows a normal distribution with a mean 25 degree and standard .deviation 4 degrees What is the probability that the temperature on one ?day will be between 23 and 27 0.6915 0.3205 0.383 0.3085
