Answer #1

Solution:

Parameters are numbers that summarize data for an entire population.

A parameters is a descriptive measure computed from an entire population of data .

Parameters is fixed unknown numerical value .

Statistics are number that summarize data from a sample that is some subset of the entire population.

Statistics is descriptive measure computed from a sample data.

A sample in a Statistics is a part or portion of a population . The goal is to estimate certain parameters.

Statistics is known number and a variable which depends on portion of the population.

Here 1.6% defective products is obtained from the sample of 400 smart card production.

Therefore 1.6% is a statistic

The value 1.6% is a statistic

Option b is correct
