Use the image to answer the question.
An illustration shows two sets of dot plots. One is titled Movie 1 and the other is Movie 2. The plots are shown as an abacus-like representation with dots in a vertical row over each number on a number line. For Movie 1, a number line with arrows on both ends ranges from 17 to 43 in increments of 1. There is 1 dot above 17, 18, 21, 22, 25, 26, 28, 29, 32, 33, 35, 36, 38, 40, and 43. There are 2 dots above 23 and 3 dots above 20. For Movie 2, the number line ranges from 24 to 50 in increments of 1. There is 1 dot above 25, 28, 32, 35, 36, 42, 43, 45, 47, 48, and 50. There are 2 dots above 30, 34, and 37, and 3 dots above 40.
The dot plots show the ages, in years, of people watching two movies at a local theater. Find the median age of the people who watched each movie.

Movie 1 = 25.5
Movie 2 = 37
The median age of the people who watched Movie 1 is 30.5.
The median age of the people who watched Movie 2 is 37.
movie 1 is wrong
Apologies for the mistake. Let's recalculate the median age for Movie 1. To find the median, we need to find the middle value.
For Movie 1, the number of data points is 15.
Since there is an odd number of data points, the median will be the middle value when the data is ordered from least to greatest.
The ordered list of ages for Movie 1 is: 17, 18, 20, 21, 22, 23, 25, 26, 28, 29, 32, 33, 35, 36, 38, 40, 43.
The middle value in the ordered list is the 8th value, which is 26.
Therefore, the correct median age of the people who watched Movie 1 is 26.
