introductory calculus class has stated that, historically, the
distribution of final exam grades in the course resemble a Normal
distribution with a mean final exam mark of μ=63μ=63% and a
standard deviation of σ=9σ=9%.
If using/finding zz-values, use three decimals.
(a) What is the probability that a random chosen
final exam mark in this course will be at least 73%? Answer to four

What's my grade? In Professor Krugman's economics course the correlation between the students' total scores prior to the final examination and their final-examination scores is r=0.5 The pre-exam totals for all students in the course have mean 280 and standard deviation 8. Professor Krugman has lost Julie's final exam but knows that her total before the exam was 300. He decides to predict her final-exam score from her pre-exam total. What is the slope of the least-square regression line of final-exam...
