True
3/6 = 0,5
1/8 = 0,125
0,5 > 0,125
B^-2/ab^-3 = b^-2/b^-3 x 1/a = b^[-2-(-3)] x 1/a = b x 1/a = b/a
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.
