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.

Answer:
Step-by-step explanation:
it is given that Square contains a chord of of the circle equal to the radius thus from diagram

If Chord is equal to radius then triangle PQR is an equilateral Triangle
Thus 
In triangle PQO applying Pythagoras theorem




Thus length of Side of square 
Area of square
Area of Circle
Ratio of square to the circle
