The x-intercepts are at 1, 0 and 3, 0. Strong positive linear association with one apparent outlier at 2. The residuals are positive, so we expect the actual values to be greater than the predicted values. Cheat sheet for Section 7. The hot water will approach room temperature but will never cool more than that. The form is linear, the direction is negative, the strength is moderate, and there are no apparent outliers. A positive residual means the pencil weighed more than was predicted by the LSRL model.

Solutions to multiple regression practice problems. Yes, the residual plot appears randomly scattered with no apparent pattern. The y-intercept is halfway between There is no solution, so the lines do not intersect. Upload document Create flashcards.

## CHEAT SHEET

Strong positive linear association with one apparent outlier at 2. Solutions to multiple regression practice problems. The hot water will approach room temperature but will never cool more than that. Yes, the residual plot appears randomly scattered with no apparent pattern.

The y-intercept is at 0, 3. One would expect to pay 0. See graph at right. The cold actually lasted 0. The predictions from the model may be too low. A positive residual means the pencil weighed more than was predicted homewokr the LSRL model.

The graph is a parabola opening upward. For complaints, use another form. An increase of pounds in weight is expected to answfrs the fuel efficiency by 8. Families which can afford the considerable expense of bottled water can also afford better nutrition and better health care.

The residuals are positive, so we expect the actual values to be greater than the predicted values. All equations are equivalent and have the same solution: The form is linear, the direction is negative, the strength is moderate, and there are no apparent outliers.

See table below; sum of the squares is 0.

The LSRL model would show the expected cost of a 16 oz burger to be 0. Math 2 Name Lesson We predict that when the pencil is so short there is no paint left, the pencil is expected to weigh 1.

The asymptote would be lower, but still parallel to the x-axis. The x-intercepts are at 1, 0 and 3, 0.

About 5 — 1. From left to right the graph is always increasing. With a car readily available these teens might simply be driving more and the extra time on the road is causing them to be in more crashes.
