Unformatted text preview: Paul Ramirez SCM HW 6 1) I learned that as a and b, the intercept and slope of the straight line, increase, the linear r FINISH THIS ONE 2) False, if the correlation between two variable is near 1, the slope doesnt necessarily have to be large but it will be positive since the correlation is greater than 0. CHECK THIS ONE 3) is the population correlation coefficient and r is the sample correlation coefficient. When r=0, there is no linear relationship in the sample. When r=-1, there is a perfect inverse (-) relationship in the sample. When r=1, there is a perfect direct (+) relationship in the sample. POPULATION PART MISSING 4) The coefficient of determination for a sample is r . It indicates the fraction of variation in the dependent variable that can be explained by the independent variable x. The in the dependent variable that can be explained by the independent variable x....
