The dots plots show the ages in years of people watching two movies at a local theater. Fin the median age of people who watch each movie
To find the median age for each movie, we first need to organize the ages in ascending order:
Movie 1: 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50
Movie 2: 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50
Now, we can find the median age for each movie:
For Movie 1, we have 34 ages listed. Since the number of ages is even, the median will be the average of the two middle values. In this case, the two middle values are the ages at positions 17 and 18, which are 25 and 26. So, the median age for Movie 1 is (25 + 26) / 2 = 25.5.
For Movie 2, we have 26 ages listed. Since the number of ages is odd, the median will be the middle value. The middle value is the age at position 13, which is 34. Therefore, the median age for Movie 2 is 34.
Therefore, the median age of people who watch Movie 1 is 25.5 years and the median age of people who watch Movie 2 is 34 years.
