Answer:
D. Testing the null hypothesis that the mean difference equals 0 is not equivalent to determining whether the confidence interval includes 0
Step-by-step explanation:
Dependent samples are samples that are related to one another.
In a hypothesis test, the hypothesis test and the confidence interval are equivalent in the sense that they result in the same conclusion.
However, in an hypothesis test , we fail to reject the null hypothesis if the rejection region is greater than the t-test statistics. It is therefore crucial to understand that if the true mean is zero. the confidence interval level for the mean of differences within the lower limit and the upper limits must contain zero , which implies the mean difference and the confidence interval are equivalent.
Answer:
0.946 liter
Step-by-step explanation:
Here, we are told to round 0.946353 to the nearest thousandth.
The nearest thousandth is simply the third value after the decimal point.
Now to successfully round this number, we need to consider the number after this number. If the number is less than 5, then we round it up as zero and add to the thousandth digit.
in the case where the fourth number is higher than or equal to 5, we turn it to 1 and add it to the thousandth number
In the case of this question however, we can see that the number is less than 5, so we can only round to 0 and this does not affect the thousandth digit .
(4, -6) e (-2, 1)
a = Δy / Δx
a = (y-yo) / (x-xo)
a = [1-(-6)] / (-2-4)
They’re equivalent because 3 • 3 is 9 and whatever you do to the top, you do to the bottom, therefore 4 • 3 is 12. That would equal 9/12.
