A student only has room for one more course in their schedule, but cannot decide between two very interesting courses. To help make the final decision, this student checks online ratings for the professors for both courses. Both professors have an average rating of 3.2. For professor A, standard deviation is 0.3, and for professor B, standard deviation is 0.6. Ratings for both professors follow a normal distribution. Keeping the averages and standard deviations listed, what range of ratings did 68% of the students give each professor? Professor A: from to Professor B: from to
