Answer:
x = -3/10
Step-by-step explanation:
<u>Step 1: Distribute</u>
-1/2(20x - 10) = 8
<em>-10x + 5 = 8</em>
<em />
<u>Step 2: Subtract 5 from both sides</u>
-10x + 5 - 5 = 8 - 5
<em>-10x = 3</em>
<em />
<u>Step 3: Divide both sides by -10</u>
-10x / -10 = 3 / -10
<em>x = -3/10</em>
<em />
Answer: x = -3/10
Answer: The confidence interval would be (120.6, 159.4).
Step-by-step explanation:
Since we have given that
n = 200
mean =
Standard deviation =
At 95% confidence interval, z = 1.96
So, 95% confidence interval would be
Hence, the confidence interval would be (120.6, 159.4).
