To calculate the percentiles of the ages of the Oscar winners for Best Actor from 2008 to 2017, count the number of values below the desired percentile and calculate the percentile using the formula provided.
The question is asking for the percentiles of the ages of the Oscar winners for Best Actor from the years 2008 to 2017. To find the percentile, we can use the formula:
Percentile = (Number of values below the desired percentile / Total number of values) * 100
For the 20th percentile, we can calculate:
Count the number of values below the 20th percentile. In this case, there are 6 values (18, 21, 22, 25, 26, 27) below the 20th percentile.
Calculate the percentile using the formula: (6 / 29) * 100 = 20.69%
For the 55th percentile, we can calculate:
Count the number of values below the 55th percentile. In this case, there are 16 values (18, 21, 22, 25, 26, 27, 29, 30, 31, 33, 36, 37, 41, 42, 47, 52) below the 55th percentile.
Calculate the percentile using the formula: (16 / 29) * 100 = 55.17%
