I really hate to do this again-

First you need to know that slope-intercept form is written as y=mx+b
b= y-intercept and m= slope
I'll first start with line number one.
First, you can see that line number one crossed the y-intercept at 2.
So far we have y=mx+2
Next to find slope either do Y2-Y1/X2-X1 or M = Rise/Run
I'll do rise/run. I picked two points. (I provided a picture) An I went up 1 and went to the right 2. Giving you a slope of 1/2. If I add this to my my slope-intercept form I would get y=mx+b. Which is D.
Just do that for the rest of them.
But, here is the Code: DGBH
Let me know if anything is incorrect!

Answer:
a) Null and alternative hypothesis:
b) A Type I error is made when a true null hypothesis is rejected. In this case, it would mean a conclusion that the proportion is significantly bigger than 10%, when in fact it is not.
c) The consequences would be that they would be more optimistic than they should about the result of the investment, expecting a proportion of students that is bigger than the true population proportion.
d) A Type II error is made when a false null hypothesis is failed to be rejected. This would mean that, although the proportion is significantly bigger than 10%, there is no enough evidence and it is concluded erroneously that the proportion is not significantly bigger than 10%
e) The consequences would be that the investment may not be made, even when the results would have been more positive than expected from the conclusion of the hypothesis test.
Step-by-step explanation:
a) The hypothesis should be carried to test if the proportion of students that would eat there at least once a week is significantly higher than 10%.
Then, the alternative or spectulative hypothesis will state this claim: that the population proportion is significantly bigger than 10%.
On the contrary, the null hypothesis will state that this proportion is not significantly higher than 10%.
This can be written as:
