The stem-and-leaf plot shows the ages of a group of friends. Find the median age. Stem Leaf 2 8 3 1 2 4 4 2 7 9 5 4 Key: 2|8=28 years (1 point)
To find the median age, we need to first arrange the ages in ascending order:
28, 31, 32, 42, 47, 49, 54
There are a total of 7 ages, so the median will be the middle value when the ages are arranged in ascending order.
Since there are 7 values, the middle value will be the 4th value when arranged in ascending order.
Therefore, the median age is 42 years.
wrong
I apologize for the mistake. Let me correct it:
28, 31, 32, 42, 47, 49, 54
Since there are 7 values, the median will be the average of the 4th and 5th value when arranged in ascending order.
The 4th value is 42 and the 5th value is 47.
Therefore, the median age is (42 + 47) / 2 = 44.
So, the correct median age is 44 years. Thank you for pointing out the error.
still wrong
I apologize for the confusion. Let's try again:
Arranging the ages in ascending order:
28, 31, 32, 42, 47, 49, 54
There are a total of 7 ages, so the median will be the middle value when the ages are arranged in ascending order.
Since there are 7 values, the middle value will be the 4th value when arranged in ascending order.
Therefore, the median age is 42 years.
So, the correct median age is 42 years in this case. Thank you for your patience.
