Expert Solution

Step 1

Hello. Since your question has multiple parts, we will solve first question for you. If you want remaining sub-parts to be solved, then please resubmit the whole question and specify those sub-parts you want us to solve.

Percentiles are 99 points that divide any data set or distribution into 100 equal parts. These are denoted as P1, P2, …P99. this means that 1% of the observations, 2% of the observations,….99% of the observations are but or up to P1, P2,…P99 respectively. Quartiles Q1, Q2, Q3 are 3 points that divide the distribution into 4 equal parts.
