Assume you begin with some distribution of data. Now, take many, many samples of size n and create a distribution of sample means from these samples.


1. What will happen to the mean of the new distribution as n gets larger and larger?

2. What will happen to the standard deviation of the new distribution as n gets larger and larger?

Suppose we repeatedly take samples of size 100 from the population distribution, calculate a sample mean each time, and plot those sample means in a histogram. The histogram we created would be an example of a (variable, population, distribution, sampling distribution???) . According to the central limit theorem, the histogram would have a shape that is approximately (left skewed, right skewed or normal???) , with mean  (give a number???) and standard deviation  (give a number??). The standard deviation of the statistic under...
