Answer: F. Statistic, because the data set of salaries of 50 employees is a sample.
Step-by-step explanation:
A parameter gives measure of a characteristic for the entire population where as a statistic gives measure of a characteristic for the subset of population (sample).
Given : The average annual salary of 50 of a company's 800 employees is $54,000.
It means the sample size = 50 and the sample mean salary= $54,000.
i.e $54,000 is giving the measure for mean salary for the sampled 50 employees.
It means $54,000 is a statistic .
Hence, the correct answer is option (F).
Answer:
2
Step-by-step explanation:
(8-x)(8+x)
8×8=64
-x·+x=-x^2
64-x^2
7844=7400(1+(8/12)r)
Solve for r
R=0.09*100=9%
