The Coast Starlight Amtrak train runs from Seattle to Los Angeles. The scatterplot below displays the distance between each stop (in miles) and the amount of time it takes to travel from one stop to another (in minutes). Describe the relationship between distance and travel time. Answer How would the relationship change if travel time was instead measured in hours, and distance was instead measured in kilometers? Answer Correlation between travel time (in miles) and distance (in minutes) is r=0.636.r=0.636. What is the correlation between travel time (in kilometers) and distance (in hours)?

If the correlation between a person’s age and annual income is 0.60, then the coefficient of determination tells us that: 36% of the variation in a person’s annual income can be explained by the predictor variable age. 36% of a person’s annual income can be explained by their age 60% of the variation in a person’s annual income can be explained by the predictor variable age 60% of a person’s annual income can be explained by their age
