The graph of the solution set for the inequality can be seen below.
<h3>How to graph the solution set?</h3>Here we have the inequality:
3x - 2y < -12
If we isolate y, we get:
3x + 12 < 2y
(3x + 12)/2 < y
(3/2)x + 6 < y
Now, we just need to graph the line y = (3/2)x + 6 with a dashed line (because the points on the line are not solutions).
And then we need to shade the region above the line.
The graph of the solution set can be seen below.

Answer:
The 95% confidence interval is
Step-by-step explanation:
From the question we are told that
The first sample size is
The first proportion
The second sample size is
The second proportion is
Given that the confidence level is 95% then the level of significance is mathematically represented as
From the normal distribution table we obtain the critical value of the value is
Now using the formula from the question to construct the 95% confidence interval we have
Here
