If we have 0 gallons of paint, we can paint 0 square feet. The vertical intercept of the regression equation says that is we have 0 gallons of paint, on average, we can paint approximately 25 square feet. Some typical reasons for this disparity are:
Select all that apply:
-variability in paint surfaces
-measurement error in paint purchased
-paint mitosis
-paint thieves
-variability in how someone paints
-measurement error in paint remaining
-black holes
-variability in paint
think about it -- why do you even have a regression equation?
variability in paint surfaces, variability in how someone paints, measurement error in paint remaining, measurement error in paint remaining??
The correct options are:
- variability in paint surfaces
- measurement error in paint purchased
- variability in how someone paints
- measurement error in paint remaining
- variability in paint
Explanation:
1. Variability in paint surfaces: Different surfaces may absorb paint differently, leading to variations in the amount of paint required to cover a certain area.
2. Measurement error in paint purchased: Sometimes, the actual quantity of paint purchased may differ slightly from the intended amount due to measurement errors or inaccuracies.
3. Variability in how someone paints: Different individuals may apply paint in different ways, leading to variations in the coverage achieved per gallon of paint.
4. Measurement error in paint remaining: It can be challenging to accurately determine the exact amount of paint remaining after a painting project, especially when dealing with partially used cans or containers.
5. Variability in paint: Different brands or types of paint may have variations in their coverage capabilities, even for the same quantity of paint.
The options "paint mitosis," "paint thieves," and "black holes" are not valid reasons for the disparity mentioned in the question. These are unrelated or fictional concepts that do not impact the coverage of paint.
