age
You should already have created a Least Squares line with Weeks on the x-axis and Age on the y-axis in the Animals Starter File.
1 What is the predictor function? y = x +
2 What is the slope?
3 What is the y-intercept?
4 How long would our line of best fit predict it would take for a 5 year-old animal to be adopted?
5 What if they were a newborn, or just 0 years old?
6 Does it make sense to find the adoption time for a newborn using this predictor function? Why or why not?
weight
Make another Least Squares Line, but this time use the animals' weight as our explanatory variable instead of their age.
7 How long would our line of best fit predict it would take for an animal weighing 21 pounds to be adopted?
8 What if they weighed 0.1 pounds?
cats
9 Using the Animals Dataset - Cats Only, make another Least Squares Line, comparing the age v. weeks columns for only the cats.
10 What is the predictor function? y = x +
11 What is the slope?
12 What is the y-intercept?
13 How does this line of best fit for cats compare to the line of best fit for all animals?
14 How long would our line of best fit predict it would take for a 5 year-old cat to be adopted?
★ Using Animals Dataset - Dogs Only, make another Least Squares line, comparing the age v. weeks columns for only the dogs.
