(b) 19% is a parameter, 22% is a statistic.

Step-by-step explanation:

-A parameter is defined as characteristic of a population under study.

In this case, the population is all cars manufactured and the characteristic of whiteness is exhibited by 19% of them.

#A statistic is a characteristic of sample.

-In this case the sample size is 100 and the statistic is 22% of them are white.

=>A statistic is usually taken or used as a representation of the entire population.
