Step 1:<span>Simplify both sides of the equation.</span><span><span>2<span>(<span><span>3x</span>+1</span>)</span></span>=<span>3<span>(<span>2−x</span>)</span></span></span><span><span><span><span>(2)</span><span>(<span>3x</span>)</span></span>+<span><span>(2)</span><span>(1)</span></span></span>=<span><span><span>(3)</span><span>(2)</span></span>+<span><span>(3)</span><span>(<span>−x</span>)</span></span></span></span>(Distribute)<span><span><span>6x</span>+2</span>=<span><span>6+</span>−<span>3x</span></span></span><span><span><span>6x</span>+2</span>=<span><span>−<span>3x</span></span>+6</span></span>
Step 2: Add 3x to both sides.<span><span><span><span>6x</span>+2</span>+<span>3x</span></span>=<span><span><span>−<span>3x</span></span>+6</span>+<span>3x</span></span></span><span><span><span>9x</span>+2</span>=6</span>
Step 3:Subtract 2 from both sides.<span><span><span><span>9x</span>+2</span>−2</span>=<span>6−2</span></span><span><span>9x</span>=4</span>
Step 4:Divide both sides by 9.<span><span><span>9x</span>9</span>=49

Answer:
- A
- A
- C
- B
Step-by-step explanation:
1) The statement is true. A larger margin of error creates a wider confidence interval, which is more likely to contain the population parameter.
2) The statement is false. A larger sample size decreases the standard error of the sample proportion, which decreases the margin of error.
3) The statement is true. A smaller sample size increases the standard error of the sample proportion, which, for a fixed margin of error, decreases the critical value, z*.
4) The statement is true. One can see from the margin of error formula that the margin of error is inversely proportional to the square root of n.
