true or false?
Over the past 50 years, there has been a strong negative correlation between average annual income and the record time to run I mile. In other words, average annual incomes have been rising while the record time to run 1 mile has been decreasing.(a) Do you think increasing incomes cause decreasing times to run the mile? Explain.(b) What lurking variables might be causing the change in one or both of the variables? Explain.
What do you mean by Simultaneous Causality? Explain in detail.

- The condition of an independent variable being correlated to one or more other independent variables is referred to as nonlinearity. statistical significance. multicollinearity. linearity.arrow_forwardDefine and distinguish among positive correlation, negative correlation, and no correlation. How do we determine the strength of a correlation? A. positive correlation means that both variables tend to increase (or decrease) together B. positive correlation means that two variables tend to change in opposite directions, with one increasing all the other decreases. C. positive correlation means that there is no apparent relationship between the two variables. D. positive correlation means that there is a good relationship between the two variables. arrow_forwardA property agent wants to study the relationship between the age of a house (X) and its selling price (Y).
