Answer:
We want to test the the claim that in general, 10% of students repeat a course and thats what we want to verify so then the system of hypothesis are:
Null hypothesis: ![p =0.1](https://tex.z-dn.net/?f=p%20%3D0.1)
Alternative hypothesis ![p \neq 0.1](https://tex.z-dn.net/?f=p%20%5Cneq%200.1)
And the best option for this case is given:
d) H0:p=0.1 vs. H1:p
0.1
Step-by-step explanation:
For this case we have the folloing info:
number of people repeating the class
the sampel size selected
the estimated proportion of people repeating the class

Answer:
79
Step-by-step explanation:
Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.
