Answer: c. 72% is a statistic and 56% is a parameter.
Step-by-step explanation:
- A population is a large group of all possible observations required for a study by the researcher's point of view.
- A Sample is a finite subset of population that is used by researcher to represent the entire population in an analysis.
- A parameter is a number that measure a characteristic for the entire population.
- A statistic is a number that measure a characteristic for the sample.
- A statistics given an estimate to the population parameter.
Given : A study of voting chose 663 registered voters at random shortly after an election.
Population of interest : "registered voters"
Sample : " 663 registered voters "
72% of 663 registered voters said they had voted in the election.
⇒ Statistic = sample proportion registered voters voted in the election.= 72%
Election records show that only 56% of registered voters voted in the election.
⇒ Parameter = Population proportion of registered voters voted in the election = 56%
Hence, the correct answer is "c. 72% is a statistic and 56% is a parameter."
Answer:
the other leg = 2 root 14, which is roughly 7.48331 cm
Step-by-step explanation:
9squared = 5squared + x
81-25=xsquared
squareroot 56 = 2 root 14
You watched 36.75 sitcom episodes and 21 drama episodes (you might have to round 36.75 to 37 i'm not sure)
It is greater because 9.76 can also be represented as 9.760, which is less than 9.768
