Answer:
8.06
Step-by-step explanation:
I used my brain and paper. I don't want to have to explain it anymore sorry but yes I think that is the right answer.
Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
Answer:
The answer is option B.
Step-by-step explanation:
B is proportional because it's adding 1/4 each time. A is not.
