If repeated samples of yogurt sales were taken, according to the Central Limit Theorem, the mean of those repeated samples would tend to be normally distributed if the sample size is large enough. Because the sample population is , it is safe to apply the Central Limit Theorem, even if the sample size for each sample is 15.

Select the reason why the Central Limit Theorem can be applied.

a.)
The sample size features 50 or more observations.
b.)
The samples are large enough, independently drawn, and done repeatedly.

c.)
The data distribution is skewed negatively.
d.)
The data distribution is skewed positively.
