One hundred years ago, the fastest cyclist finished a course at an average speed of about 25.4 kph. In 2005, another cyclist averaged 41.8 kph for the fastest average winning speed in history. Complete parts a through c below. Click the icon for the average speed of the winner for each year the competition was held. Describe the relationship of Avg Speed by Year, being careful to point out any unusual features in the plot. A. The relationship is positive, with a moderate amount of scatter. There is a general nonlinear trend. B. The relationship is positive, with a moderate amount of scatter. There is a general nonlinear trend, with no races from 1915 to 1918 or from 1940 to 1946 because of world wars. C. The relationship is positive, with a moderate amount of scatter. There is a general linear trend, with no races from 1915 to 1918 or from 1940 to 1946 because of world wars. O D. The relationship is positive, with a moderate amount of scatter. There is a general linear trend. b) Find the regression equation of Avg Speed on Year. Avg Speed = + • Year (Round the constant to two decimal places as needed. Round the Year coefficient to three decimal places as needed.) c) Are the conditions for regression met? A. No. The relationship is not straight enough in the early part of the 20th century to fit a regression line. The variables are quantitative, and there are no real outliers. B. No. The variables are quantitative, the plot seems straight enough to fit a linear relationship, there are no real outliers. C. Yes. The relationship is not straight enough in the early part of the 20th century to fit a regression line. The variables are quantitative, and there are no real outliers.
