Question

The table shows the relationship between time spent running and distance traveled in which type of model best describes the relationship

Answer 1

A on E2020

Explanation:

Answer 2

Relationship is linear as r is closest to 1.

Explanation:

From statistics we know that,

`\text{Corelation Coefficient}=r=(n(\sum xy)-(\sum x)(\sum y))/(√([n\sum x^2-(\sum x)^2][n\sum y^2-(\sum y)^2]]))`

Putting all the values from the table,

we get corelation factor as 0.9995

Therefore, the relationship is linear as r is closest to 1.
