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.

<u>Answer:</u>
The value of m is by using quadratic formula
<u>Solution:</u>
Given, expression is
Now, we have to solve the above given expression.
By multiplying the equation with m, we get
Now, let us use quadratic formula
Here in our problem, a = 12, b = 20, c = -3
Hence the value of m is by using quadratic formula
