Answer: No, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
Step-by-step explanation:
Since we have given that
n = 1400
x = 154
So,
and p = 0.10
So, hypothesis would be
So, the test statistic value would be
At 5% level of significance,
critical value would be 1.96.
Since 1.96>1.25.
so, we will accept the null hypothesis.
Hence, no, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
Answer:
The point (x, y) = (3, -4) represents the solution of the given system of equations.
Please check the attached graph.
Step-by-step explanation:
Given the system of equations
Please check the attached graph of the given system of equations
From the graph:
- The red line represents the equation:
- The blue line represents the equation:
Point of Intersection:
- We know that the point of intersection of two lines represents the solution of the system of equations.
It is clear from the attached graph that the two lines intersect at the point (-4, 3).
i.e. at x = -4, y = 3
Therefore, the point (x, y) = (3, -4) represents the solution of the given system of equations.
Please check the attached graph.
