A statistician is curious if the gold medal time for the women's 100 - meter freestyle depends upon the year that the Summer Olympics took place. A sample of every other Summer Olympics for the women's 100-meter freestyle produced the following data:

Year/Time (in seconds)

1912/82.2

1924/72.4

1932/66.8

1952/66.8

1960/61.2

1968/60.0

1976/55.65

1984/55.92

1992/54.64

2000/53.8

2008/ 53.1

Using your calculator, create a scatter plot of the data. Use the gold medal time as the response variable and the year of the Summer Olympics as the explanatory variable.
