Answer: 8H=T
Step-by-step explanation:
8 is dependant on the hours so you put it together. Your independent
value is T since it is by itself. So your answer becomes.
8H=T
Answer:
(a) Normal model
![(b)\ Mean = 0.58](https://tex.z-dn.net/?f=%28b%29%5C%20Mean%20%3D%200.58)
![(c)\ \sigma = 0.0165](https://tex.z-dn.net/?f=%28c%29%5C%20%5Csigma%20%3D%200.0165)
Step-by-step explanation:
Given
![p = 58\%](https://tex.z-dn.net/?f=p%20%3D%2058%5C%25)
![n = 900](https://tex.z-dn.net/?f=n%20%3D%20900)
Solving (a): The distribution type
The sample follows a normal model
Solving (b): The mean
This is calculated as:
![Mean = p](https://tex.z-dn.net/?f=Mean%20%3D%20p)
So, we have:
![Mean = 58\%](https://tex.z-dn.net/?f=Mean%20%3D%2058%5C%25)
Express as decimal
![Mean = 0.58](https://tex.z-dn.net/?f=Mean%20%3D%200.58)
Solving (c): The standard deviation
This is calculated as:
![\sigma = \sqrt{\frac{p(1 - p)}{n}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B%5Cfrac%7Bp%281%20-%20p%29%7D%7Bn%7D%7D)
So, we have:
![\sigma = \sqrt{\frac{58\%(1 - 58\%)}{900}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B%5Cfrac%7B58%5C%25%281%20-%2058%5C%25%29%7D%7B900%7D%7D)
Express as decimals
![\sigma = \sqrt{\frac{0.58(1 - 0.58)}{900}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B%5Cfrac%7B0.58%281%20-%200.58%29%7D%7B900%7D%7D)
![\sigma = \sqrt{\frac{0.58 * 0.42}{900}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B%5Cfrac%7B0.58%20%2A%200.42%7D%7B900%7D%7D)
![\sigma = \sqrt{\frac{0.2436}{900}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B%5Cfrac%7B0.2436%7D%7B900%7D%7D)
![\sigma = \sqrt{0.00027066666}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B0.00027066666%7D)
![\sigma = 0.0165](https://tex.z-dn.net/?f=%5Csigma%20%3D%200.0165)
