The dot plots shows ages and years of people watching two movies at a local theater. Find the median age of the people who watched each movie.
To find the median age of the people who watched each movie, we need to find the middle value in the data set. In a dot plot, this is the value that falls directly in the middle of the data when arranged in numerical order.
Let's analyze the dot plots for each movie:
Movie A:
9, 12, 13, 15, 18, 20, 22, 25, 29, 31
The ages are already in numerical order, and there are 10 total values. The middle value is the 5th value, which is 18. Therefore, the median age of people who watched Movie A is 18.
Movie B:
16, 18, 22, 24, 26, 28, 30, 33, 35, 38
The ages are already in numerical order, and there are 10 total values. The middle value is the 5th value, which is 26. Therefore, the median age of people who watched Movie B is 26.
