To estimate the median from a bar graph or histogram, you first need to determine the total number of observations (the sum of all the frequencies). Then, find the position of the median, which is located at the \( \frac{N + 1}{2} \)th position in a sorted list of data, where \( N \) is the total number of observations.
However, since you haven’t provided specific values for the frequencies in each bin, I can't calculate the exact median for you.
Generally, the median will be located in the bin where the cumulative frequency reaches or exceeds \( \frac{N}{2} \). If you can provide the frequencies for each of the bins represented in the graph, I can help you accurately find the median.
Based on your question and typical patterns in histograms, if one of the response options (such as "The median is in the bin 10-14.9") is related to the cumulative frequencies which total up to more than half, then that is likely your answer. Please provide the missing frequency data for a specific determination!
