B. The correlation coefficient

C. The intercept

D. The number of times Kanye West interrupts acceptance speeches

A social psychologist did a study examining whether length of court trials (X) in days predicts length of time for juries to come to a decision (Y) in hours. The resulting regression equation is: Ŷ= 4 + (0.33)(X). What is the interpretation of the regression coefficient?

Group of answer choices

A. For every 1 day increase in court trial, juries are predicted to take an additional 4 hours.

B. For every 1 day increase in court trial, juries are predicted to take an additional .33 hours

C. For every .33 day increase in court trial, juries are predicted to take an additional 4 hours.

D. For every 4 day increase in court trial, juries are predicted to take an addition .33 hours of deliberation.

Group of answer choices

A. The effect size principle

B. The linear principle

C. The least squared error principle

D. Skinner, the Principal from the Simpsons
