Chapter 5: Q. 73 (page 352)

For each probability and percentile problem, draw the picture.

When age is rounded to the nearest year, do the data stay continuous, or do they become discrete? Why?

Short Answer

Expert verified

The data remains continuous because it cannot be approximated.

Step by step solution

01

Definition of probability and Percentile in Age 

Percentile and probability are the key components of statistical problems that are used in the interpretation of data. Age is also a type of data that requires the calculation of probability and percentile for gaining an understanding of people's life duration and various other aspects related to it. These calculations are used broadly in everyday life to calculate values for test score or indicates various health-related factors.

02

Calculation and Justification

Percentiles can be calculated using the formula n=(P/100)xN

Therefore, if the age is rounded to the year that is near to the age then the approximate value of it cannot be calculated. Thus, the data that are calculated from the equation remains continuous in nature.
