Answer: you can’t really answer this because you have to how many bags of flour and how many boxes of butter that you have and then youll be able to solve
Step-by-step explanation: maybe if you reword it and edit your question then it’ll make more sense
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)
D. combine like terms, 4+7 is 11 and -3 and -10 is -13
