Question

the table shows the weight of a dog in pounds at various ages in months. age vs. weight of a dog age in months weight in pounds 3 2 4 5 6 7 8 10 9 11 12 15 what values should be entered for x and y into a regression calculator to find the equation of the trend line? x: 3, 4, 6, 8, 9, 12 y: 2, 5, 7, 10, 11, 15 x: 3, 4, 6, 8, 9, 15 y: 2, 5, 7, 10, 11, 12

Explanation:

Step1: Recall regression input rules

In regression analysis, the independent variable (the variable we think affects the other) is \(x\), and the dependent variable (the variable that is affected) is \(y\).

Step2: Identify independent and dependent variables

Here, age (in months) is the independent variable (as age changes and likely affects weight), so age values go into \(x\). Weight (in pounds) is the dependent variable, so weight values go into \(y\).

Answer:

First option: \(x:3,4,6,8,9,12\); \(y:2,5,7,10,11,15\)
