Answer: The professor was not accurate with his hypothesis.
Null hypothesis: P1 = 12.5%, P2 = 42.5%, P3 = 45%
The alternate hypothesis: At least one proportion of the student will differ from the others.
Step-by-step explanation: To check if the professors hypothesis were inaccurate.
What percentage of student bought a hard copy of the book.
(25 ÷ 200) × 100 = 12.5%
What percentage of the student printed it from the web.
(85 ÷ 200) × 100 = 42.5%
What percentage of the students read it online.
(90 ÷ 200) × 100 = 45%
This means that the professor was not accurate with his hypothesis. Because the proportion of student in his hypothesis was not the same in the actual.
Therefore; the null hypothesis are
P1 = 12.5%, P2 = 42.5%, P3 = 45%
The alternative hypothesis will state that at least one of the proportion will be different from the others.
C=+3 since your adding three more onto four
The answer is B: moderate
3x + 3 = 0 //Subtract -3 on both sides
3x = -3 //Divide 3 on both sides
x = -1
Here x = -1 and y is all the values where x = -1, so basically from negative infinity to infinity.
Make sure when writing the solution, y is any value and x stays the same.
Solution: (-1,0) and (-1,1)
//Hope this helps
