Answer: The lower bound of confidence interval would be 0.116.
Step-by-step explanation:
Since we have given that
p = 13.2%= 0.132
n = 1105
At 90% confidence,
z = 1.645
So, Margin of error would be
So, the lower bound of the confidence interval would be
Hence, the lower bound of confidence interval would be 0.116.
Look at the picture.
We know, the sum of the measures of the triangle is equal 180°.
Therefore in ΔBCD we have:
<em>subtract 137 from both sides</em>
Answer: x° = 90°, y° = 43°.
