Answer:
c) 72% is a statistic and 56% is a parameter.
Step-by-step explanation:
Previous concepts
A statistic or sample statistic "is any quantity computed from values in a sample", for example the sample mean, sample proportion and standard deviation
A parameter is "any numerical quantity that characterizes a given population or some aspect of it".
Solution to the problem
For this case we know that they select a sample of 663 registered voters and the sample proportion from these registered voters is:
representing the sample proportion of people who voted in the election
They info that they have is that the true proportion before is
and that represent a value related to the population.
So on this case the 0.72 represent a statistic since represent the sample and the 0.52 is a value who represent the population for this case is a parameter.
So the correct option is:
c) 72% is a statistic and 56% is a parameter.

Answer:
the answer i got was 501600
Step-by-step explanation:
I divided 330000 by 100 and then multiplied that answer by 4 and then times that by 13.
It would be 8

because you have to multiply the exponent by each of the numbers exponents. you may not see it but 2 has a 1 as an exponent and so does r. 1 time 3 is 3 for each therefore each number now has an exponent of 3 and we got rid of the outside exponent. now all you have to do is simplify the 2 to the power of 3 which gives you 8 and that is all
11x2=22
22x6=132
I believe the answer is 132
