Silvers Gym: Student Coaching Slides 1 Question 1: Regression Analysis Y = a + bX, X is given,

Y is predicted 2 Question 1: Excel Steps Go to web site to get data Click Data, then Data Analysis on right (If not in menu, click Add-ins, Analysis Tool Pak) Regression, OK

Click labels Enter two columns of numbers Note: dialog box has Y before X 3 Question 1: Regression Equation

Bottom table, Column = Coefficients Row = intercept =a Row = cholesterol = b = slope Interpret slope: If X increases by 1 unit, Y changes (increases? decreases?) by b units 4

Question 1: Coefficient of Determination Top table Row = R square Interpret: R-square per cent of total variation in Y is explained by variation in X 5

Questions 2: Expected Value E(X) =xP(x) Hint: Add constant value to E(x) to get total cost 6 Question 3:

Find Mean Mean = age at which average person experiences incident = Normal: Z = (x-)/ Value of Z from normal table in statistics book Use algebra to solve for 7

Question 4: Expected Number of Lives Saved = Expected number still alive due to defibrillator minus expected number who died due to improper use Hint: Use reasoning, not algebraic formula 8

Question 5: Negligence Define Prima Facie Case Plaintiffs Burden Defenses Defendants Burden 9 Prima Facie Case

Conduct Duty Breach of Duty Actual (direct) Cause

Proximate (legal) Cause Damage 10 Conduct What Did Silvers Do or Fail to Do? Affirmative Action Omission Failure to Act 11

not Have Suffered the Loss Easy, Difficult, or Impossible Burden in this Case? 16 Proximate (Legal) Cause Policy Determination Should Defendant Really be Responsible
