Answer and Step-by-step explanation:
Solve for b.
A = ![(\frac{1}{2}) (h)(a+b)](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B2%7D%29%20%28h%29%28a%2Bb%29)
Divide by h and multiply by 2 from both sides.
![\frac{2A}{h} = a+ b](https://tex.z-dn.net/?f=%5Cfrac%7B2A%7D%7Bh%7D%20%3D%20a%2B%20b)
Subtract a from both sides.
![(\frac{2A}{h} ) - a = b](https://tex.z-dn.net/?f=%28%5Cfrac%7B2A%7D%7Bh%7D%20%29%20-%20a%20%3D%20b)
Answer:
19
Step-by-step explanation:
64 - 45 = 19
64 is the highest water collection time, while 45 is the lowest water collection time. You can tell by looking at the two lines at the end and beginning of the box plot.
Answer:
The slope of the line is 1 , because the slope of another line parrallel to it is 1 and we know the when two lines are parralel the slope are equal
Answer:
![\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE](https://tex.z-dn.net/?f=%5Chat%20p_1%20-%5Chat%20p_2%20%5Cpm%20z_%7B%5Calpha%2F2%7D%20SE)
And for this case the confidence interval is given by:
![0.11 \leq p_1 -p_2 \leq 0.39](https://tex.z-dn.net/?f=0.11%20%5Cleq%20p_1%20-p_2%20%5Cleq%200.39)
Since the confidenc einterval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal
Step-by-step explanation:
Let p1 and p2 the population proportions of interest and let
and
the estimators for the proportions we know that the confidence interval for the difference of proportions is given by this formula:
![\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE](https://tex.z-dn.net/?f=%5Chat%20p_1%20-%5Chat%20p_2%20%5Cpm%20z_%7B%5Calpha%2F2%7D%20SE)
And for this case the confidence interval is given by:
![0.11 \leq p_1 -p_2 \leq 0.39](https://tex.z-dn.net/?f=0.11%20%5Cleq%20p_1%20-p_2%20%5Cleq%200.39)
Since the confidence interval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal
