To solve this problem, you have to find the arithmetic mean of a set of numbers that are derived from set \( X \) based on the conditions provided: 1. Multiply by 2. 2. Subtract by 3. 3. Multiply by -3. 4. Divide by -3. Follow these steps to find the arithmetic mean for each condition: 1. **Multiply by 2:** - Each number in set \( X \) will be doubled. Calculate the mean of \( X \) and then double it. 2. **Subtract by 3:** - Subtract 3 from each number in set \( X \). Calculate the mean of \( X \) and then subtract 3. 3. **Multiply by -3:** - Each number in set \( X \) will be tripled and negated. Calculate the mean of \( X \) and then multiply by -3. 4. **Divide by -3:** - Each number in set \( X \) will be divided by -3. Calculate the mean of \( X \) and then divide by -3. Once you apply these transformations, you can calculate the arithmetic mean for each case.
