1. For the following sets of data, determine if a linear regression is a good fit (strong correlation) or not a good fit (weak correlation). If the linear regression is a good fit, write the equation for the regression line. Include a picture of your calculator screen with just the scatterplot (weak correlation) or the scatterplot and regression line (strong correlation) in your work submitted.

a. Is a linear regression a good fit? (yeso)

b. If yes, what's the equation? If no, type "none".

c. Did you take a picture of your calculator screen to be submitted to the Dropbox? (yeso)
