Answer:
125.74 units
Step-by-step explanation:
30.18 units
33.00 units
28.38 units
34.18 units
125.74
4x+1 = 2x+7
4x-2x = 7-1
2x = 6
x= 6/2
x= 3
This can be factored as (x-3)^2, so they are equal
Answer: The explanation is correct.
Step-by-step explanation:
The interpretation of 95% confidence interval for population mean is that "A person can be 95% sure that the true population mean lies in it."
Given : The admissions director from Big City University found that (107.8, 116.2) is a 95% confidence interval for the mean IQ score of all freshmen.
Interpretation: The admissions director can be 95% sure that the true population mean IQ score of all freshmen lies in (107.8, 116.2).
i.e. There is a 95% probability (chance) that the interval from 107.8 to 116.2 contains μ.
Hence, the explanation is absolutely "correct" .
