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).
Thanks for taking the time to read Which equation of the least squares regression line most closely matches the data set A ŷ 10 1x 118 8 B ŷ 0 31x 37.
