6- (15%) Assume that X= The final grade of a student in Stochastic Modeling class and Y= The final grade of a student in Structural Analysis class. The joint probability of the grades earned by a student is P(X,Y) which is as follows.
Structural Analysis Grades Stochastic Modeling Grades: 95, 80, 90, 0.2, 0.4, 75, 0.3, 0.1
How the grades of Stochastic and Structural Analysis classes are related to each other? (Positive, Negative or no relationship?) *Hint: No need for the final value of ρ. Do necessary calculations to show how X and Y are related to each other (Positive, Negative or no relationship)

Many classes calculate a final grade by using a weighted scoring system. For example, “Assignments” might be worth 40% of your final grade. To calculate the grade for the Assignments category, the teacher takes the percentage earned on the assignments and multiplies it by the weight. So if the student earned a 90% total on the Assignments, the teacher would take 90% x 40, which means the student earned a 36 percent on the Assignments section. The teacher then calculates...

An analysis of the final test scores in this class shows that the scores follow the normal distribution. The mean of the distribution is 85 and the standard deviation is 6. The professor wants to award an A student whose score is in the highest 11% which means 89% of the class will have lower grades. What is the cut-off point (or score) for those students who earn an A versus those that earn a B? In other words, what...
