Question

Kardal used the trend line to predict that a man 72 inches tall would wear about a size 10.5 shoe. What can be concluded about this prediction? Check all that apply.

Answer 1

the higher they are in inches the larger size their shoe

Answer 2

Hi, and welcome to QuestionCove!
For a question like this, which involves a diagram (the "trend line" in question), it would be very helpful for us if we could also see the diagram. Please feel free to attach a copy or screenshot using the "Attach File" button after you make your post.
Without seeing the "trend line", it's hard to know how to answer the question or even exactly what it is asking, but I think NineTailedFox's input about taller people needing larger shoe size is a reasonable assumption to start with; this will probably be shown by the trend line as well, once you post that @s27837426

Answer 3

Choices:

The prediction is not reasonable.

The prediction is an interpolation.

No data is given in the scatterplot for a height of 72
inches, but a shoe size can still be predicted.

A prediction cannot be made without the linear
regression equation.

A 72-inch tall man will wear a size 11.5 shoe.

Answer 4

hint: 72 inches *is* within the data provided, so it's an interpolation (as opposed to an extrapolation). there's one other correct answer choice - do you think the prediction is reasonable, based on the trendline, or not?
