Answer:
A sample size of 6755 or higher would be appropriate.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error M is given by:
90% confidence level
So , z is the value of Z that has a pvalue of , so .
52% of Independents in the sample opposed the public option.
This means that
If we wanted to estimate this number to within 1% with 90% confidence, what would be an appropriate sample size?
Sample size of size n or higher when . So
A sample size of 6755 or higher would be appropriate.
Answer:
$12579.84
Step-by-step explanation:
Anna deposited $10,000 into an account three years ago.
The first year she earned 12 percent interest
Interest = 12% of 10000 =
Amount at the end of first year = 10000+1200 = 11200
The second year she earned 8 percent interest
Interest = 8% of 11200 =
Amount at the end of second year = 11200+896 = 12096
The third year she earned 4 percent interest.
Interest = 4% of 12096 =
Amount at the end of third year = 12096+483.84 = 12579.84
Hence she have $12579.84 in her account today
