To find the equation of the trend line using a regression calculator, you need to input the values for the age in months (denoted as [tex]\(x\)[/tex]) and the corresponding weight in pounds (denoted as [tex]\(y\)[/tex]). These values are taken directly from the given table of data.
The values of [tex]\(x\)[/tex] (age in months) are:
[tex]\[ x = [3, 4, 6, 8, 9, 12] \][/tex]
The values of [tex]\(y\)[/tex] (weight in pounds) are:
[tex]\[ y = [2, 5, 7, 10, 11, 15] \][/tex]
So, you should enter the following datasets into the regression calculator:
- For [tex]\(x\)[/tex] (Age in months): 3, 4, 6, 8, 9, 12
- For [tex]\(y\)[/tex] (Weight in pounds): 2, 5, 7, 10, 11, 15
By entering these values, the regression calculator will be able to compute the trend line equation that best fits the given data points.
