Solution Summary

This answers a multiple choice question on a regression equation, including a detailed explanation.

PRICE VS. AGE: A LINEAR REGRESSION:
investigate the relationship and perform a linear regression statistical analysis on sample data collected. The objective behind the analysis is to answer the research question of is there a relationship between the age of car owners and the price of their cars.
Hypothesis Statement
One o

Question 1
Show us a scatterplot between two interval level variables. (Use Excel to chart them.) Are the results bunched together or far apart? Is the relationship linear? Is the relationship non-linear? Is there no apparent relationship between the two variables?
Question 2
We use Pearson's correlation coefficie

Ten students in a graduate program were randomly selected. Their grade point averages (GPAs) when they entered the program were between 3.5 and 4.0.
The following data were obtained regarding their GPAs on entering the program versus their current GPAs:

When we carry out a regression, we assume a direct causal relationship. In a correlation analysis, we don't make such an assumption, but nevertheless determine whether 2 variables are related. Briefly explain how two variables can be correlated without one directly influencing the other (=without causal relationship)
