I'm not sure what the options are as this appears to be a multiple choice question, but this probability is as follows:
15 + 0.2x = 20 + 0.15x
0.05x = 5
x = 100 miles
Answer:
Step-by-step explanation:
-1/2x -7=-11
-1/2x +4=0
4=1/2x
x=8
If the sample size is 1488 and confidence interval of 99% then the margin of error is 0.03088.
Given sample size of 1488, percentage of those polled own a home be 69% and confidence level be 99%.
We are required to find the approximate margin of error.
Margin of error is the difference between calculated values and real values.
n=1488
p=0.69
Margin of error=z*
Z score when confidence level is 99%=2.576.
Margin of error=2.576*
=2.576*
=2.576*
=2.576*
=2.576*0.01198
=0.03088
Hence if the sample size is 1488 and confidence interval of 99% then the margin of error is 0.03088.
