K Use a graphing calculator to find a linear regression model for the men's 100-meter freestyle data given in the table on the right, where x is years since 1980 and y is winning time (in seconds). Do the same for the women's 100-meter freestyle data. Do these models indicate that the women will eventually catch up with the men? The men's linear regression model is y= 0 (Round regression coefficients to three decimal places as needed.) The women's linear regression model is y = (Round regression coefficients to three decimal places as needed.)

Current Attempt in Progress A biologist collected data on a sample of 20 porcupines. She wants to be able to predict the body mass of a porcupine (M, in grams) based on the length of the porcupine (L, in cm). Her least squares regression equation is M = 3089 +175.6L. Predict the body mass of a porcupine that is 51 cm long. Report your answer using one decimal place. 5661.0 g 5732.5 g O 5866.6 g 6139.2 g Save for Later Last saved 1 second ago.
