List numbers: List all the numbers from the stem-and-leaf plot: 12,15,15,16,20,21,24,25,29,29,35.
Count total: Count the total number of observations to find the median position:There are 11 observations.
Calculate median: Calculate the median position: egin{equation}(11 + 1) / 2 = 6^{\text{th}} \text{position}.\end{equation}
Identify median: Identify the median value:The 6th value in the ordered list is 21.
Find less than: Find numbers less than the median:Numbers less than 21 are 12, 15, 15, 16, and 20.
Match to options: Match the numbers less than the median to the options given: (A) 18 is not in the list, (B) 21 is the median, (C) 25 is greater than the median, (D) 26 is greater than the median, (E) 29 is greater than the median, (F) 35 is greater than the median.
Realize mistake: Realize a mistake was made in the previous step because we didn't compare the correct numbers to the median.
