Answer:
47% is the statistic and 31% is the parameter.
Step-by-step explanation:
A parameter is a quantity of a variable representing certain characteristic of a population.
A statistic is a quantity of a variable representing certain characteristic of a sample.
The sample of parents of kindergartners selected is, <em>n</em> = 345.
The School records show that only 31% of parents of kindergartners sent their children to pre-kindergarten.
That is the population proportion is, <em>p</em> = 0.31.
This is the parameter value.
Of the 349 parents, 47% said they sent their children to pre-kindergarten.
That is the sample proportion is,
= 0.47.
This is the statistic value.
Thus, the correct option is:
47% is the statistic and 31% is the parameter.
