Play an AI-generated podcast conversation about this lesson

What does the coefficient estimate for water content in the linear regression model represent?

The standard deviation

The error term

The slope of the line (correct)

The intercept of the line

What does a t value close to 0 indicate for the intercept in the linear regression model?

Error in the data

Inconsistent results

No impact on calorific value (correct)

Significant impact on calorific value

What does a high standard error for a coefficient in a linear regression model imply?

Measurement error in the data

No impact on the model

High reliability of the coefficient estimate

Low reliability of the coefficient estimate (correct)
