Does there seem to be a linear trend?
O A. Yes, because the scatterplot shows an approximate linear pattern.
B. No, because the scatterplot shows an obvious curved line.
OC. No, because the scatterplot does not show any obvious pattern.
D. Yes, because the scatterplot does not show any obvious pattern.
(b) Estimate the linear equation using least squares. Interpret the fitted intercept and slope. Be sure to include their units. Note if either estimate represents a large extrapolation and is
consequently not reliable.
Complete the equation for the fitted line below.
