Step-by-step explanation:
Answer:
<h2>116</h2>
Step-by-step explanation:
103 1/2 + 12 = 115 1/2
1/2 + 115 1/2 = 116.
Answer:
a
The null hypothesis is ![H_o : p = 0.67](https://tex.z-dn.net/?f=H_o%20%20%3A%20%20p%20%3D%20%200.67)
The alternative hypothesis is ![H_a : p \ne 0.67](https://tex.z-dn.net/?f=H_a%20%3A%20p%20%5Cne%200.67)
b
The sample proportion is ![\^ p = 0.65](https://tex.z-dn.net/?f=%5C%5E%20p%20%20%3D%20%200.65)
Step-by-step explanation:
From the question we are told that
The sample size is n = 546
The number of people that use a laptop overnight is ![k = 355](https://tex.z-dn.net/?f=k%20%3D%20355)
The population proportion is ![p = \frac{2}{3} = 0.67](https://tex.z-dn.net/?f=p%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%20%3D%20%200.67)
Generally
The null hypothesis is ![H_o : p = 0.67](https://tex.z-dn.net/?f=H_o%20%20%3A%20%20p%20%3D%20%200.67)
The alternative hypothesis is ![H_a : p \ne 0.67](https://tex.z-dn.net/?f=H_a%20%3A%20p%20%5Cne%200.67)
Gnerally the sample proportion is mathematically represented as
![\^ p = \frac{ k}{n}](https://tex.z-dn.net/?f=%5C%5E%20p%20%20%3D%20%20%5Cfrac%7B%20k%7D%7Bn%7D)
=> ![\^ p = \frac{ 355}{546}](https://tex.z-dn.net/?f=%5C%5E%20p%20%20%3D%20%20%5Cfrac%7B%20355%7D%7B546%7D)
=> ![\^ p = 0.65](https://tex.z-dn.net/?f=%5C%5E%20p%20%20%3D%20%200.65)
I can help, but what are you exactly trying to do here?
3/4 = 12/16
12/16 is obviously bigger than 11/16... so 3/4 is bigger
