This study guide covers hypothesis testing for regression slopes, focusing on the t-test for slopes. It explains setting up null (H₀) and alternative (Hₐ) hypotheses about the population slope (β). Finally, it reviews the necessary conditions for conducting this test, including linearity and equal variance.

Question 1 of 7
What is the primary purpose of using a t-test for the slope of a regression line? 🧐
To determine the strength of the correlation between variables
To test if the y-intercept is significantly different from zero
To determine if there is a statistically significant linear relationship between variables
To predict future values of the response variable
