The pth percentile is a value such that approximately a. p percent of the observations are less than the value and (100 - p) percent are more than this value. b. (100 - p) percent of the observations are less than the value and p percent are more than this value. c. (100 - p) percent of the observations are less than the value and (100 - p) percent are more than this value. d. p percent of the observations are less than the value and p percent are more than this value.

p percent of the observations are less than the value and (100 - p) percent are more than this value.

Step-by-step explanation:

Given : The pth percentile is a value such that approximately

Solution :

Definition : A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls

So, The pth percentile means p percentage of observations in a group of observations falls bellow the value

So, (100-p) percentage of observations in a group of observations falls above the value

So, Option a is true

Hence p percent of the observations are less than the value and (100 - p) percent are more than this value.
