A more accurate reason would be that the sample was not big enough to represent the population as a whole, the best answer is "No, because the sample was not random"

Sedaia [141]

Answer:

Jeff went over by 53.33 grams or $53\frac{1}{3}$ grams.

Step-by-step explanation:

Jeff is baking a cake. The recipe says that he has to mix 32 grams of vanilla powder to the flour.

Jeff knows that 1 cup of that particular vanilla powder has a mass of 128 grams.

He added $\frac{2}{3}$ of a cup of vanilla powder to the flour.

So, he added a mass of $\frac{2}{3} \times128= 85.33$ grams of vanilla.

As the recipe says, it needs 32 grams of vanilla so Jeff went over by $85.33-32=53.33$ grams.

Jeff went over by 53.33 grams or $53\frac{1}{3}$ grams.
