Final answer:
The median neonatal mortality estimate from a dot plot requires the specific estimates in ascending order, and since the actual dot plot data isn't provided, we cannot determine the median.
Step-by-step explanation:
To identify the median neonatal mortality estimate from the dot plot provided for 12 randomly selected nations, we would arrange the data points in ascending order and find the middle value. With an even number of data points (12 in this case), the median would be the average of the 6th and 7th values. However, without the actual dot plot data, it's impossible to determine the median. To answer such a question, the dot plot is essential, as it provides the specific neonatal mortality estimates needed to calculate the median.
