Answer: 0.893
Step-by-step explanation:
Given : Sample size of residential water bills: n=100
Number of residences had reduced their water consumption over that of the previous year = 80
Then sample proportion: ![\hat{p}=\dfrac{80}{100}=0.8](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D%5Cdfrac%7B80%7D%7B100%7D%3D0.8)
Critical value for 98% confidence= ![z_{\alpha/2}=2.326](https://tex.z-dn.net/?f=z_%7B%5Calpha%2F2%7D%3D2.326)
The upper bound for confidence interval for population proportion :
![\hat{p}+ z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%2B%20z_%7B%5Calpha%2F2%7D%5Csqrt%7B%5Cdfrac%7B%5Chat%7Bp%7D%281-%5Chat%7Bp%7D%29%7D%7Bn%7D%7D)
![=0.8+ (2.326)\sqrt{\dfrac{0.8(1-0.8)}{100}}\\\\=0.8+0.09304=0.89304\approx0.893](https://tex.z-dn.net/?f=%3D0.8%2B%20%282.326%29%5Csqrt%7B%5Cdfrac%7B0.8%281-0.8%29%7D%7B100%7D%7D%5C%5C%5C%5C%3D0.8%2B0.09304%3D0.89304%5Capprox0.893)
Hence, the 98% upper confidence bound for the proportion of residences that reduced their water consumption.=0.893
Answer:
$1860
Step-by-step explanation:
(12,400{total money} - (12,400{total money} x (1/4) {Mary's cut})) / 5{number of children splitting the remains}
OR
(12400 x 0.75) / 5
Well the answer is 14 cm, because all you have to do is divide the length of LN in half
