Question 8: A new set of test scores is: 85, 88, 90, 92, 94. The scores are all rounded to the nearest ten and are all even numbers. What is the median score?

Answer: 90

Question 9: Construct a set of six even numbers where the median is 15. Is this possible? Explain why or why not.

Answer: No, because median of an even set must be the average of the two middle numbers, which must both be even, so median cannot be 15.

Question 10: Identify the mistake in this set: 2, 4, 6, 8, 10, 13. Find the correct median.

Answer: The median should be the average of 8 and 10, which is 9. The set's median is 9, but the set contains an odd number, so to have an even median, the set should be adjusted to include even numbers only.

Question 11: Find two even numbers between 50 and 60 such that when added to the set {52, 54, 56, 58}, the median remains unchanged.

Answer: 48 and 60

Question 12: Challenge: Create a set of eight even numbers where the median is exactly 20. Provide the set.

Answer: Example set: 14, 16, 18, 20, 20, 22, 24, 26
