(Optional use of technology.) The accompanying graph shows the world distance records for the womens long jump. Several times a new long jump record was set more than once during a given year. a. Generate a line that approximates the data by hand or, if using technology, use the data from the Excel or graph link file LONGJUMP. (Set 1950 or 1954 as year 0). Interpret the slope of your line in this context. If you are using technology, specify the correlation coefficient. b. If the world record distances continue to change at the rate described in your linear model, predict the world record distance for the womens long jump in the year 2010. Check on the Internet. c. What would your model predict for the record in 1943? How does this compare with the actual 1943 record of 6.25 meters? What do you think would be a reasonable domain for your model? What do you think the data would look like for years outside your specified domain?
