It is thought that a linear relationship may exist between x and y. (Check that you have entered the data rectly.) X 0.8 2.5 1.1 3.7 6.6 9.2 5.1 6.5 5.0 2.2 find the least squares line for this sample. b) find the first residual (the residual associated with (0.8, 9.2). What percentage of the variability in y is explained by the variability in x? the ANOVA F-test for this data, state d) the alternative hypothesis, e) the critical value and f) the observed ue of the test statistic.
