Calculate the 20th 50th and 80th percentiles for the followi

Calculate the 20th, 50th, and 80th percentiles for the following data set (Round your answers to 1 decimal place.) 127 160 136 280 208 155 252

The given number is ordered from least to greatest :-127,136,155,160,208,252,280

The total number of values is 7

Now the 20th percentile is 20% of 7 =.2*7=1.4

Rounding to the nearest number it is 1

Therefore the 20th percentile is number 127

b)50th percentile is the middle number =.5*7=3.5 or rounding to the nearest integer it is 4 which is equal to 160

c)80th percentile=.8*7=5.6 on rounding we get 6.Thus the 6th number from left to right is 252

Answer is 20th percentile =127

50th percentile =160

80th percentile =252
