Answer:
Hypothesis

P-value = 0.078
Conclusion: The null hypothesis is rejected. There is enough evidence to claim that the proportion of foreigners home buyers is different from 26%.
Step-by-step explanation:
We will perform a hypothesis test on a proportion.
The null hypothesis states that 26% of home buyers are foreigners.
The alternative hypothesis states that the proportion is different than 26%.

The significance level is α=0.10.
The sample proportion is:

The standard error is:

Then, we can calculate the z-statistic as:

The P-value can be calculated as:

The P-value is smaller than the significance level, so the effect is significant.
The null hypothesis is rejected. There is enough evidence to claim that the proportion of foreigners home buyers is different from 26%.
Error = 1/2(Maximum range - Minimum range) = 1/2(3.2-1.1) = % = 0.0105
If p is the point estimator;
Then,
Minimum range = p - Error
Maximum range = p + Error
Solving one of the two expressions,
0.011 = p - 0.0105 => p = 0.011+0.0105 = 0.0215 = 2.15%
Answer:
y = 9x-8
Step-by-step explanation:
Find y values for x= -3 and x = 3. These will come out to -35 and 19 respectively.
Plug these numbers into the rise/run equation for slope m (y2-y1)/ (x2-x1). Plugging values in and simplifying you will get 54/6, which reduces to 9. This is your m value.
Apply your m value to x = 3 going backwards (x = 2 gives a y value of 10, 1 gives 1, and 0 gives -8). This will give you a y intercept of -8. This is your b value.
Plug the slope and y intercept into the mx + b equation. This will give you y = 9x-8.
There you go!
