Response:
We define a line L.
In a two-dimensional space, a line can be expressed as follows:
y = a*x + b
where 'a' denotes the slope and 'b' represents the y-intercept.
To determine the slope for a line passing through points (x1, y1) and (x2, y2), the formula is:
a = (y2 - y1)/(x2 - x1).
Using one of these points will help to find the value of 'b'.
Once we have the line's equation:
y = a*x + b
we can substitute in a specific point (x, y)
to verify if the equation holds true. If it does, that point lies on the line L.
We aim to verify the assertion that generally, 10% of students repeat a course, leading us to this hypothesis setup:
Null hypothesis:
Alternative hypothesis.
The most fitting choice for this scenario is:
d) H0:p=0.1 vs. H1:p ≠ 0.1.
For this case, the provided information includes: the number of students repeating the course, the selected sample size, and the estimated proportion of repeaters. We are testing the claim that generally, 10% of students retake classes, which will be validated through established hypotheses.
