A professor at a local university noted that the grades of her students were normally distributed with a mean of 73 and a standard deviation of 11.
Answer the following questions rounding your solutions to 4 decimal places.
The professor has informed the class that 7.93 percent of her students received grades of A. What is the minimum score needed to receive a grade of A?
Homework Answers
z value at 7.93% = -1.41
z= (x - mean)/s
1.41 = (x - 73)/11
x = 11 * 1.41 + 73
x = 88.5100

1) The grades of students in a class are distributed normally. The average grade of the students in this class is 65; standard deviation is 2. The students who take the teacher give more points by making "systematic error". What is the passing score since it gives more than 25% of the class score in total? Calculate.

3.2.21. A professor in a large statistics class has a grading policy such that only the 15% of the students with the highest scores will receive the grade A. The mean score for this class is 72 with a standard deviation of 6. Assuming that all the grades for this class follow a normal probability distribution, what is the minimum score that a student in this class has to get to receive an A grade?
