Ok this is easy the triangle that is 1/3 shaded is the least shaded out of the two just draw your self a picture of two = triangles and split one into fourths and the other into thirds then shade three parts the one split into fourths and one part of the one split into thirds and you will see that the triangle split into thirds is the least shaded hope this helped

f(x)=3√x f ( x ) = x 3
Step-by-step explanation:
Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, we have the following confidence interval of proportions.
![\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}](https://tex.z-dn.net/?f=%5Cpi%20%5Cpm%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D)
In which
Z is the zscore that has a pvalue of
.
For this problem, we have that:
![n = 1000, \pi = 0.60](https://tex.z-dn.net/?f=n%20%3D%201000%2C%20%5Cpi%20%3D%200.60)
90% confidence interval
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
![\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.60 - 1.645\sqrt{\frac{0.60*0.40}{1000}} = 0.575](https://tex.z-dn.net/?f=%5Cpi%20-%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D%20%3D%200.60%20-%201.645%5Csqrt%7B%5Cfrac%7B0.60%2A0.40%7D%7B1000%7D%7D%20%3D%200.575)
The upper limit of this interval is:
![\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.60 + 1.645\sqrt{\frac{0.60*0.40}{1000}} {119}} = 0.625](https://tex.z-dn.net/?f=%5Cpi%20%2B%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D%20%3D%200.60%20%2B%201.645%5Csqrt%7B%5Cfrac%7B0.60%2A0.40%7D%7B1000%7D%7D%20%7B119%7D%7D%20%3D%200.625)
The 90% confidence interval is 0.575 to 0.625.
