**Understanding Statistical Concepts** 1. **Define expected value of the mean:** - The expected value is the weighted average of the values in the range. 2. **When working with a distribution of sample means, standard deviation is replaced with what term?** - Expected value 3. **If a normal distribution has a population mean of 50, what is the expected value of the distribution of sample means?** 4. **For a population with a mean of 80 and a standard deviation of 20, compute the standard error (SE) for each of the following:** - a. \( n = 8 \) - b. \( n = 16 \) - c. \( n = 25 \) 5. **For a sample of \( n = 25 \) scores, what is the value of the population standard deviation necessary to produce each of the following standard error values?** - a. 10 points - b. 5 points
