Answer:
[0.4979, 0.5479]
Step-by-step explanation:
-We first determine the sample proportion:
-The confidence intervals of a sample proportion is calculated using the formula:
#We substitute for the sample proportion and z value to get the Confidence interval:
![CI=\hat p\pm z\sqrt{\frac{\hat p(1-\hat p}{n}}\\\\=0.5238\pm 1.645\times \sqrt{\frac{0.5238\times0.4762}{1008}}\\\\=0.5238\pm0.0259\\\\=[0.4979,0.5497]](https://tex.z-dn.net/?f=CI%3D%5Chat%20p%5Cpm%20z%5Csqrt%7B%5Cfrac%7B%5Chat%20p%281-%5Chat%20p%7D%7Bn%7D%7D%5C%5C%5C%5C%3D0.5238%5Cpm%201.645%5Ctimes%20%5Csqrt%7B%5Cfrac%7B0.5238%5Ctimes0.4762%7D%7B1008%7D%7D%5C%5C%5C%5C%3D0.5238%5Cpm0.0259%5C%5C%5C%5C%3D%5B0.4979%2C0.5497%5D)
Hence, the 90% confidence intervals is [0.4979,0.5479]
Answer:
-7.5
Step-by-step explanation:
I used a calculator
Answer:
x = -2,1, 2
Step-by-step explanation:
g(x) = (x + 2)(x − 1)(x − 2)
Assuming we are looking for the roots
0 = (x + 2)(x − 1)(x − 2)
Using the zero product property
0 = x+2 0 =x-1 0 = x-2
x=-2 x = 1 x =2
A=4
B=0
C=7
X=16
This is what I think
Answer:
1) 2
2) 4
3) 3
4) 1
Step-by-step explanation:
8/4 is 2
8/2 is 4
3/1 is pretty simply 3
And lastly (and kind of least)...
3/3 is 1
Hope this helped you out!
