Tanzania [10]
Answer:
![y = -\frac{2}{5}\cdot x - 11](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B2%7D%7B5%7D%5Ccdot%20x%20-%2011)
Step-by-step explanation:
First, the slope is determined by using the following expression:
![m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![m = \frac{-7-(-9)}{-10 - (-5)}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-7-%28-9%29%7D%7B-10%20-%20%28-5%29%7D)
![m = -\frac{2}{5}](https://tex.z-dn.net/?f=m%20%3D%20-%5Cfrac%7B2%7D%7B5%7D)
The y-intercept is found by using the line equation, the slope and one point:
![y = m \cdot x +b](https://tex.z-dn.net/?f=y%20%3D%20m%20%5Ccdot%20x%20%2Bb)
![b = y - m\cdot x](https://tex.z-dn.net/?f=b%20%3D%20y%20-%20m%5Ccdot%20x)
![b = -7 - \left(-\frac{2}{5}\right)\cdot (-10)](https://tex.z-dn.net/?f=b%20%3D%20-7%20-%20%5Cleft%28-%5Cfrac%7B2%7D%7B5%7D%5Cright%29%5Ccdot%20%28-10%29)
![b = -11](https://tex.z-dn.net/?f=b%20%3D%20-11)
The equation of the line is:
![y = -\frac{2}{5}\cdot x - 11](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B2%7D%7B5%7D%5Ccdot%20x%20-%2011)
Answer:
it's too blurryyyyyyyyyyyyyyyyyyyyy
Answer:
C) There is not sufficient evidence to support the claim that the mean attendance is greater than 523.
Step-by-step explanation:
Let μ be the the average attendance at games of the football team
The claim: the average attendance at games is over 523
Null and alternative hypotheses are:
: μ=523
: μ>523
The conclusion is failure to reject the null hypothesis.
This means that <em>test statistic</em> is lower than <em>critical value</em>. Therefore it is not significant, there is no significant evidence to accept the <em>alternative</em> hypothesis.
That is no significant evidence that the average attendance at games of the football team is greater than 523.
