before analyzing the data above, is there evidence that any assumptions for regression could be violated in this data set? the data points in the middle of the plot appear to be outliers violating normality there are many clumps in the data set suggesting the data was not independent there appears to be a fan shape, which suggests constant variance is violated zero is not in the middle, 63 is the middle residual which violates the best fit there is a swerve in the data going non-linear both up and down at the same time correct: your answer is correct. assume no assumptions are violated. form a 78% confidence interval for how much your final is supposed to increase for each problem done on homework 9.
