Best ResponseYou've already chosen the best response.0The table below shows the distance y, in miles, traveled by a toy car in x minutes: Time (x) (minutes) 20 30 40 50 Distance (y) (miles) 5 10 15 20 Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and distance traveled by the toy car. (4 points) [Choose the value of correlation coefficient from 1, 0.8, 0.5, 0.02] Part B: What is the value of the slope of the graph of distance versus time, and what does the slope represent? (3 points) Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)

Best ResponseYou've already chosen the best response.3First, plot the points. (20, 5), (30, 10), (40, 15), (50, 20) A. You'll see that it's a perfectly straight line, so it's a perfect positive correlation  Positive because it increases from left to right. The value to represent this is 1. A correlation of 1 means time and distance have a perfect positive linear relationship, meaning if x increases by a certain value, y also increases by a certain value at the same time. In our case, every time x increases by 10, y increases by 5. B. Pick any two points and plug them into the slope formula. Lets use (20, 5) and (30, 10). m = (y₂  y₁) / (x₂  x₁) = (10  5) / (30  20) = 5/10 = 1/2 The slope represents the rate (or speed). Distance, rate, and time are related by distance = rate • time distance / time = rate rise / run = m 1/2 = m The car's speed is 1/2 miles per minute. C. It's not causation because x must cause y to change, or vice versa. The car's distance has no effect on time. Time will increase steadily no matter what. Time has no effect on the car's distance. The car's movement is due to batteries, not because of time. It's a correlation because x and y are related by a common pattern mentioned in part A.

Best ResponseYou've already chosen the best response.0correlation coefficient is 1 slope is 5/10 which reduces to 1/2 not sure about the 3rd one
