Consider a sample with data values of 27, 24, 21, 16, 30, 35, 28, and 24. Compute the 20th, 25th, 65th, and 75th percentiles. 20th percentile 1 1.8 Incorrect: Your answer is incorrect. 25th percentile 2 2.25 Incorrect: Your answer is incorrect. 65th percentile 3 5.85 Incorrect: Your answer is incorrect. 75th percentile

20

21.75

27.85

29.5

Step-by-step explanation:

Arranging the values in ascending order we get

1621242427283035

n = Number of values = 8

Rank is given by

Taking the fraction of the rank i.e., 0.8 and work out the weighted mean

The 20th percentile is 20

The 25th percentile is 21.75

The 65th percentile is 27.85

The 75th percentile is 29.5
