A sample of 100 roller coaters examines the relationship between top speed (response) and max drop (explanatory). Based off of the fitted vs residual plot below, select all the assumption have been violated.

The Equal Variance Assumption

There aren’t any outliers.

Both variables are quantitative

The relationship is linear

From the plot it is clear that assumption 1 and 2 are violated. That is, the assumption of equal variance ( homoscedasticity) and there aren't any outliers.

Step-by-step explanation:

Both variables are quantitative  and The relationship is linear have not been violated.
