1. Because the distribution of sample proportions has a Normal shape under many conditions, we can apply the Empirical Rule. Let's practice doing this here, with our distribution based on samples of size n = 60. If you recall from the figure above, this distribution was Normal in shape, with a mean of 0.25 and a standard deviation of 0.056.

1. Approximately 68% of samples of size n = 60 have proportions of brown candies between ___________ and _____________.

2. Approximately 95% of samples of size n = 60 have proportions of brown candies between ___________ and _____________.

3. Approximately 99.7% of samples of size n = 60 have proportions of brown candies between ___________ and _____________.
