Answer:
The inequality would be $49 + g is less than $55
Step-by-step explanation:
I think that g would be 1 because that would make the bill $52 and it says that he wants to keep the bill under $55 not the same as $55
Answer:
There no sufficient evidence to support the manufactures claim at the 0.05 level
Step-by-step explanation:
From the question we are told that
The mean is ![\mu = 22100 \ miles](https://tex.z-dn.net/?f=%5Cmu%20%20%3D%20%2022100%20%5C%20miles)
The sample mean is ![\= x = 23400 \ miles](https://tex.z-dn.net/?f=%5C%3D%20x%20%20%3D%20%2023400%20%5C%20miles)
The sample size is ![n = 18](https://tex.z-dn.net/?f=n%20%20%3D%2018)
The standard deviation is ![\sigma = 1 500 miles](https://tex.z-dn.net/?f=%5Csigma%20%20%3D%20%201%20500%20miles)
The test statistics is ![t = 3.677](https://tex.z-dn.net/?f=t%20%3D%203.677)
The level of significance is ![\alpha = 0.05](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%20%200.05)
The null hypothesis is ![H_o : \mu = 22100](https://tex.z-dn.net/?f=H_o%20%3A%20%20%5Cmu%20%3D%20%2022100)
The alternative hypothesis is ![H_a : \mu \ne 22100](https://tex.z-dn.net/?f=H_a%20%3A%20%20%5Cmu%20%20%5Cne%2022100)
Generally the p-value is mathematically represented as
![p-value = 2 * P(t >3.677 )](https://tex.z-dn.net/?f=p-value%20%20%3D%20%202%20%2A%20%20P%28t%20%3E3.677%20%29)
From the z-table ![P(t >3.677 ) = 0.000118](https://tex.z-dn.net/?f=P%28t%20%3E3.677%20%29%20%20%3D%20%200.000118)
So
![p-value = 2 * 0.000118](https://tex.z-dn.net/?f=p-value%20%20%3D%20%202%20%2A%20%200.000118)
=>
From he value given and obtained we see that ![p-value < \alpha](https://tex.z-dn.net/?f=p-value%20%20%3C%20%20%5Calpha)
Hence we reject the null hypothesis
Hence there no sufficient evidence to support the manufactures claim
Answer:
The answer is 2.8
Step-by-step explanation:
5/100 = n/56
56 x 5 = 280
280/100 = 2.8
