Determine if the correlation between the two given variables is likely to be positive or negative, or if they are not likely to display a linear relationship.
The age of a vehicle and cost of maintenance
Homework Answers
As the age of vehicle increases, the cost of maintenance also increases due to wear out impacts on the vehicles. So, the two variable are positively correlated and are likely to display a strong linear relationship.

Consider a two-dimensional scatterplot representing the relationship between two continuous variables. If the correlation coefficient is -1, then: a. All points lie in a straight line with a slope of -1. b. All points lie in a straight line with an unknown negative slope. c. All points do not lie in a straight line but the best fitting regression line has a slope of -1. d. There is a strong positive relationship between the two variables.

A research analyst states that the correlation between two variables is statistically significant from zero (with r = 0.85). Which of the following conclusion is appropriate? High values of one variable tend to be associated with low values of the other variable. For every unit of change in one variable tend to be associated with .85 values of the other variable. (C) Any association between the two variables does not appear to be linear. (D) 0.85 indicates...
