In his MTH173 class, Professor Fibonacci found that the mean score of the first test was 92. Suppose that the scores are normally distributed with a standard deviation of 9 points. What is the probability that a randomly selected score is less than 86? P(x < 86) = What is the probability that a randomly selected score is more than 90? P(x > 90) = what is the probability that a randomly selected score is between 86 and 90? P(86x90): CL In his MTH173 class, Professor Fibonacci found that the mean score of the first test was 92.
