Straight enough condition:
[ Select ] ["The
residuals plot shows a curved pattern.", "The spread of the
residuals is not consistent.", "The scatterplot is not
straight."]
Independence assumption:
[ Select ] ["The
residuals plot shows a curved pattern.", "The scatterplot is not
straight.", "The spread of the residuals is not
consistent."]
Equal variance assumption:
[ Select ] ["The
residuals plot shows a curved pattern.", "The spread of the
residuals is not consistent.", "The scatterplot is not
straight."]
Nearly Normal condition, outlier
condition: [
Select ] ["The histogram of the residuals
is skewed to right", "The histogram of the residuals is skewed to
left"] with one possible outlier.
These data are [ Select
] ["not appropriate",
"appropriate"] for inference.
Further analysis of the data for the breakfast cereals in Exercise 23.41 looked for an association between Fiber content and Calories by attempting to construct a linear model. Here are several graphs. Which of the assumptions for inference are violated?
