Answer:
A. We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of population mean.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
99% confidence interval means that we are 99% sure that this interval contains the population mean.
Interval between 4.1 and 5.6.
So the correct answer is given by option A.

Answer: 250000
Step-by-step explanation:
Answer: 60
Step-by-step explanation:
the answer is fx=60
3x + 1 = 2x + 6

x + 1 = 6
subtract 1 from both sides
x = 5
The value of x is B. 5.
