### Statistical Analysis: Mean and Standard Deviation For the following situation, perform statistical calculations to understand the distribution of a population and its samples. #### Objective: 1. Find the mean and standard deviation of the population. 2. List all possible samples (with replacement) of the specified size from the population and determine the mean of each. 3. Calculate the mean and standard deviation of the sampling distribution. 4. Compare these with the mean and standard deviation of the population. #### Data Provided: - The word counts of five essays: 500, 634, 553, 610, and 582. - Sample size to use: 2. ### Steps: 1. **Calculate the Mean and Standard Deviation of the Population:** - Use the word counts provided for the essays. 2. **List all Possible Samples:** - Since sampling is with replacement, determine all combinations of samples of size 2 from the word counts and calculate the mean for each sample. 3. **Calculate the Mean and Standard Deviation of the Sampling Distribution:** - Use the sample means to find the overall mean and standard deviation. 4. **Comparison:** - Compare the statistical characteristics of the sampling distribution with those of the original population. This exercise helps understand the relationship between a population and its sampling distributions, reinforcing key concepts in statistical analysis. ### Note: To complete the analysis, you can use statistical formulas or software to perform the calculations accurately. Make sure to verify each step for correctness and clarity.
