If you have any questions, let me know!
What is the fourth persons time and, with these numbers it should be anything lower than 9.75.
C. 8
You substitute 8 into x, which makes the equation 5(8-5) = 15. 8-5 is 3, and 5 x 3 = 15.
Answer: B. We are 95% confident that the population parameter is between the lower confidence limit and upper confidence limit.
Step-by-step explanation:
In statistics, we know that the interpretation of
level of confidence interval is that we are
sure that the true population parameter lies in it.
Therefore, the proper interpretation of a 95% confidence interval is that we are 95% confident that the population parameter is between the lower confidence limit and upper confidence limit.
Answer:
f = 2
Step-by-step explanation:
2 +1.25f = 10 -2.75f
Add 2.75f to each side
2 +1.25f+ 2.75f = 10 -2.75f+2.75f
2 +4f = 10
Subtract 2 from each side
2+4f-2 = 10-2
4f = 8
Divide each side by 4
4f/4 = 8/4
f = 2
