Answer:
a=6.9
Step-by-step explanation:
a(2)+4(2)=8(2)
4×4=16 8×8=64
16-16 64-16
a(2)=6.9

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."
The <em>correct answer</em> is:
This should be a uniform distribution.
Explanation:
Each of the sections labeled 1 through 5 would have the same probability of being landed on. This means that their relative frequencies should be nearly, if not exactly, the same.
When graphing this as a bar graph, it would be nearly level across the entire graph. This is called a uniform distribution, since the values are very close to (if not exactly) the same.
