This math topic focuses on calculating the mean of a set of numbers after removing a specific value, which helps in understanding the impact of data removal on central tendency. It contains problems where students need to identify which value can be removed from a set of integers to achieve a pre-specified mean. This exercise is part of a broader unit on advanced Probability and Statistics, specifically dealing with mean, median, and mode. Each question presents a different set of numbers and a target mean, and the students must choose the correct number to remove from multiple choices provided.
