Let's investigate this Spotify question for a second time in this problem set. You run the following regression: Popularity - Bo + B₂ Danceability + Now your friend says that a song's danceability is also related to it's tempo (how fast the song is). And since you aren't controlling for this in your model, your results are biased. Suppose the following facts: . On average, faster songs are more danceable. . On average, faster songs are more popular. A. Does this model suffer from omitted variable bias? either "YES" or "NO", B. If you sign the omitted variable bias expression, what is the sign of Ba? Answer either "Positive" or "Negative" Answer

![Let's investigate this Spotify question for a second time in this problem set. You run
the following regression:
Popularity = Bo + B₁ Danceability +
Now your friend says that a song's danceability is also related to it's tempo (how fast
the song is). And since you aren't controlling for this in your model, your results are
biased. Suppose the following facts:
• On average, faster songs are more danceable.
. On average, faster songs are more popular.
A. Does this model suffer from omitted variable bias?
either "YES" or "NO".
B. If you sign the omitted variable bias expression, what is the sign of B₂?
Answer either "Positive" or "Negative"
