For the Old Faithful study, which of the following statement accurately describe the results of the requirement check for inference involving a linear regression? (Select all that apply.) Group of answer choices There is a linear relationship between the variables because the scatterplot shows a "hot dog" shape and the residual plot shows random scatter (no pattern). There is not a linear relationship between the variables because the scatterplot does not show a "hot dog" shape and the residual plot shows a clear pattern. The error term is normal because the histogram of residuals is does not show a distinct or extreme departure from a normal shape. The error term is not normal because the histogram of residuals is shows a distinct or extreme departure from a normal shape. The variance is constant because the residual plot does not have a megaphone shape. The variance is not constant because the residual plot has a megaphone shape
