Given are five observations for two variables, x and y. xi 5 13 7 21 19 yi 59 42 55 10 29 -select your answer- choices: a. (A, B, C, D) the different graphs are being attached b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? There appears to be a (positive, negative) linear relationship between x and y. c. Try to approximate the relationship between x and y by drawing a straight line through the data. (Many different straight lines can be drawn, Only one straight line can be drawn, A straight line cannot be drawn) to provide a linear approximation of the relationship between x and y. D & E questions are being attached. Thank you!
Which one of the following statements is false? To compute r, the form of the relationship should be linear. If you correlate two quantitative variables, called “x” and “y,” changing the units of measurement for “x” and “y” will not change the correlation between “x” and “y.” If you correlate two quantitative variables, called “x” and “y,” the correlation will not change if you switch which variable is “x” and which is “y.” The correlation coefficient is affected by outliers. If two quantitative variables are strongly correlated, we should conclude that one variable causes the other.
