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."
Start out with 24 and then move onto dividing 24 by 3/4 your answer should be 32
3,600 divided by 4 = 900 šquare méters.
Sort the data from the smallest one.
42, 55, 69, 74, 78, 83, 83, 97, 99
There are 9 data, n = 9
Find the location of Q₂
Q₂ location = (n + 1)/2
Q₂ location = (9 + 1)/2
Q₂ location = 10/2
Q₂ location = 5
The location of Q₂ is in the fifth order
42 first order
55 second order
69 third order
74 fourth order
78 fifth order
etc
So the Q₂ or the median is 78
