Linear Regression

Q1: What type of relationship, if any, is apparent between media sexism and political ambition?
Form Hypotheses
In this study, we want to know if there is any relationship media sexism and women’s political ambition.
We will be performing two linear regressions: one for each response variable.
Q2: What are the null and alternative hypotheses of your linear regressions?
Perform Linear Regressions
Individually, perform the linear regression for media sexism and political ambition (as represented by the
number of candidates) using the lm() and summary() functions in R.
As a group, identify the parameters of your linear regression.
Q3: What is the equation of your linear regression for media sexism and candidates?
Now, perform a linear regression for media sexism and political ambition (as represented by the number of
seats) using the lm() and summary() functions in R.
Q4: What is the equation of the linear regression for media sexism and seats?
Q5: Include your scatterplots, with your regression line.
