The mean is approximately 39.9 (rounded to one decimal place).
The median age is 35.
To find the mean and median for the given data, let's first organize the data in ascending order:
22,24,25,25,27,27,28,29,30,32,32,32,33,34,34,35,35,35,37,40,40,43,44,45,47,48,50,56,61,62,67,73,79
Now, let's calculate the mean and median.
Mean (Average):
Mean= Sum of all ages/ Number of data points
et's add up all the ages first:
40+43+35+32+28+27+32+33+30+73+35+29+34+30+44+62+48+50+32+37+40+34+61+35+45+22+25+67+40+24+25+27+32+47+79+34+56=1331
Mean≈ 1331/36 ≈40.3333.
So, the mean is approximately 40.3333 (rounded to one decimal place).
Median:
The median is the middle value in a sorted list of numbers. To find the median, first, we need to arrange the ages in ascending order.
Sorted list of ages:
22,24,25,25,27,27,28,29,30,32,32,32,33,30,34,34,35,35,35,37,40,40,43,44,45,47,48,50,56,61,62,67,73,79
There are 37 ages, so the middle two values are at positions 18 and 19. The median is the average of these two middle values:
37+1/ 2 =19.
So, the median is the 19th value in the ordered list, which is 35.
Therefore, the median is 35.
In summary:
Mean: 40.3333 (rounded to one decimal place)
Median: 35
