Solution
The correct option is B Average rating of old recipe is better than new recipe. Given:
Average rating for the new recipe
= (3/5 + 5/5 + 4/5 + 2/5 + 4/5) ÷ 5
= 18/25
= 0.72
Similarly,
Average rating for the old recipe
= (0.7 + 0.65 + 0.88 + 0.75 + 0.8) ÷ 5
= 3.78 /5
= 0.756
Since 0.756 > 0.72, the average rating of old recipe is better than the new recipe.
