(a) An unweighted linear regression analysis for the three data sets gives
nearly identical results. To three significant figures, each data set
has a slope of 0.500 and a y-intercept of 3.00. The standard devia-
tions in the slope and the y-intercept are 0.118 and 1.125 for each
data set. All three standard deviations about the regression are 1.24.
Based on these results for a linear regression analysis, comment on
the similarity of the data sets.
(b) Complete a linear regression analysis for each data set and verify
that the results from part (a) are correct. Construct a residual plot
for each data set. Do these plots change your conclusion from part
(a)? Explain.
(c) Plot each data set along with the regression line and comment on
your results.
(d) Data set 3 appears to contain an outlier. Remove the apparent out-
lier and reanalyze the data using a linear regression. Comment on
your result.
(e) Briefly comment on the importance of visually examining your
data.
