To find the age that represents the 48th percentile, first arrange all the ages in ascending order:
43, 45, 48, 50, 52, 52, 52, 52, 53, 58, 58, 61, 62, 67, 67
Next, calculate the position of the 48th percentile:
Percentile = (48/100) * n
Percentile = (0.48) * 15
Percentile = 7.2
Since the 48th percentile position falls between the 7th and 8th values,
we find the ages at positions 7 and 8 in our arranged list:
Age at position 7: 52
Age at position 8: 52
To calculate the age that represents the 48th percentile, we can take the average of the ages at positions 7 and 8:
(52 + 52) / 2 = 52
Therefore, the age that represents the 48th percentile is 52.
Given the following data, find the age that represents the 48th percentile.
