Suppose we took samples of employees with 30 employees in each sample. If the average satisfaction level is .614 with a standard deviation of .254.
- What would be the shape of the sampling distribution if we took these samples over and over again and recorded the means of each sample mean?

A. Suppose you take a sample of size n from a population and calculate a statistic from that sample. The statistic could be a sample proportion p, a sample mean x, or another statistic. Then suppose we repeat this process over and over again until we find all possible samples of size n from the population (this is a theoretical idea) and we calculate the same statistic from 1. each sample. The collection of all of the statistics calculated is...

Suppose we had found that the variable giving the amount of grant money raised by the charity in the last year follows a right skewed distribution with mean equal to $500,000 and standard deviation equal to $850,000. This is hypothetical. We did not actually measure the variable. We look at the average amount of grant money raised by 40 randomly sampled charities from the charity navigator website. 2.
