Question

Using the LSRL model, estimate the volume of a gas 2.5, 4.5, and 6.5 atmospheres

Answer 1

Answer:

Brett is working in the chemistry lab trying to determine if he can predict the volume of three different gases (nitrogen, oxygen, and carbon dioxide) based upon the pressure applied to them. He kept all other characteristics of the gases constant. Brett performed the following analysis:

9-60 Graph

9-60 Residuals

Discuss the association, including slope and -squared.

Hint (a):

What is the residual with the greatest magnitude and what point does it belong to?

Hint (b):

Answer (b):

Using the LSRL model, estimate the volume of a gas at , and atmospheres. Use an appropriate precision.

Hint (c):

Answer (c):

How well would this linear model work in predicting more extreme pressures? Support your answer.

Hint (d):
