Answer :
Final answer:
The correct least squares regression line equation from the dataset is ŷ = -173.51 + 4.83x, which does not match any of the options given (a-d).
Explanation:
The equation for the least squares regression line that most closely matches the dataset provided is none of the options given (a-d). The correct equation of the best-fit line as presented in the question data is ŷ = -173.51 + 4.83x. To identify the closest equation from a set of options, you would compare the slope and y-intercept of each option with those of the given equation. However, none of the choices match the provided slope of 4.83 and y-intercept of -173.51.
Additionally, a least squares regression line is a statistical method used to determine a line of best fit by minimizing the sum of the squares of the residuals (the differences between observed and predicted values).
