Look at the picture.
The equation:
10x - 15 = 6x + 9 <em>add 15 to both sides</em>
10x = 6x + 24 <em>subtract 6x from both sides</em>
4x = 24 <em>divide both sides by 4</em>
<h3>
x = 6</h3>
Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0): 
Alternative hypothesis (H1): 
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no
