The following 4 parts relate to this scenario and data.

A professor wishes to develop a numerical method for giving grades. He intends to base the on homework, two tests, a project, and a final. He wishes the final to have the largest influence on the grade. He wants the project to have 20%, each test to have 10%, and the homework to have 20% of the influence on the semester grade.

1. Determine the weights the professor should use to produce a weighted average for grading purposes. (Give answer as a whole number, not a fraction - assume it's a percent)

Final Project Test 1 Test 2 Homework
% %    % % %

For a student with the grades below, calculate a weighted average for the course.

Final Project Test 1 Test 2 Homework
62 94 69 65 84

2. What is the weighted average of the student's grade? (Round to one decimal place as needed)

This question relates to the question above, with the same data.

Final Project test 1 Test 2 Homework
62 94 69 65 84

3. Calculate the unweighted average.   (Round to one decimal place as needed)

4. Why is the weighted average preferable here? Choose the correct answer below.

a. Without weighing a student could get a grade over 100%

b. The weighted average reflects the​ professor's desire for the project to have the most impact on the grade. The weighted average here is closer to the​ student's higher performance on the project than the unweighted average is.

c. The professor is grading on a curve.

d. The weighted average reflects the professor's desire for the final to have the most impact on the grade. The weighted average here is closer to the student's low performance on the final than the unweighted average is.

Professor Moriarty has never taken a formal statistics course; however, he has heard about the bell-shaped curve and has some knowledge of the Empirical Rule for normal distributions. Professor Moriarty teaches as Honors Quantum Physics class in which he grades on the bell curve. He assigns letter grades to his students' tests by assuming a normal distribution and utilizing the Empirical Rule. The Professor reasons that if IQ and SAT scores follow a normal distribution, then his students' scores must...
