Chapter 10, Problem 1CR
The table below shows the winning times (in seconds) for the men’s and women’s 100-meter runs in the Summer Olympics from 1928 to 2016. (Source: The International Association of Athletics Federations)
- (a) Display the data in a
scatter plot , calculate thecorrelation coefficient r, and describe the type of correlation. - (b) At a = 0.05, is there enough evidence to conclude that there is a significant
linear correlation between the winning times for the men’s and women’s 100-meter runs? - (c) Find the equation of the regression line for the data. Draw the regression line on the scatter plot.
- (d) Use the regression equation to predict the women’s 100-meter time when the men’s 100-meter time is 9.90 seconds.
