... the remaining 12 contain a $5 bill. It’s easy to determine, then, that the mean contribution in these 16 envelopes is $4. As part of StreetArt’s analysis, they wish to compute the variance of the value of these 16 contributions. The value of the variance for the collection of 16 envelopes is a) 1/3 ...

Topic 18: The Central Limit Theorem 41
... In the past two topics you have discovered that sample statistics (such as proportions and means) vary from sample to sample according to a predictable long-run pattern. In many situations, this pattern follows a normal distribution centered at the population parameter. Thus, you can use your knowle ...
