Step by step solution

01

Definition

In statistics, the percentiles are the partition values. Percentile divides the entire data into 100equal parts. The 50thpercentiles denote median and below this value lies 50%of data. Similarly 60thpercentile will have 60%of data below it.

02

Explanation

The cost for repair $1700is on the upper side among all possible repair costs since this cost is in 90thpercentile. So this much of higher cost of repair gives pleasant for the manufacturer but it is very unpleasant for the consumer.

90thpercentile means if we divide all possible repair prices into100separate divisions this$1700is in at the90th position of all possible repair prices.
