A study has been conducted to find out if the wine label has an effect on the wine-tasting results.

In the study, the exact same wine was poured from two different bottles.

The first bottle labeled the wine as table wine, which is generally cheaper. The wine-tasting score is captured under the RATE1 variable.

The second bottle labeled the wine as grand cru, which is the most superior grade of wine. The score is captured under the RATE2 variable.

500 participants were invited to rate the two wines.

Perform a hypothesis testing and find out if the label has an effect on the wine tasting score.
