Answer:
We are 95% confident that the percentage of registered voters in the nation planning on voting for Robert Smith is between 49% and 55%.
Step-by-step explanation:
Given that :
Margin of Error = ±3%
Sample Proportion = 52%
Confidence level = 95%
The 95% confidence interval is :
Sample proportion ± margin of error
52% ± 3%
Lower boundary = 52% - 3% = 49%
Upper boundary = 52% + 3% = 55%
The interpretation is that at a given confidence level ; the popukation proportion based on the sample proportion and margin of error is in the confidence interval.
That equals 48 since you would just have to multiply 8 6 times like how the question stated. I hope that this helped
Answer:
1/4+1/6-3/4
lcd=12
1x3/4x3 + 1x2/6x2 - 3x3/4x3
3/12+2/12-9/12
3+2-9/12
-4/12
-1/3
Divide 4 on both sides. 276 divided by 4 equals 69. final answer: w=69
