A polling organization announces that the proportion of American voters who favor congressional term limits is 64 percent, with

kvasek [131]

Answer:

We are 95% confident that the proportion of American voters who favor congressional term limits is 64 percent with a difference of 3% for small sample size.

Step-by-step explanation:

95 % confidence means that we are 95 % confident that the the proportion of American voters who favor congressional term limits is 64 percent.

95 % confidence means that of all the sample about 95 % values are within in the given range.

And only 5% sample are not included in the given parameter.

Margin of error is the amount of miscalculation or difference in change of circumstances from the obtained data.

3% margin of error usually occurs when the data size is small.

As the data size increases the margin of error decreases.

So this statement tells us that we are 95% confident that the proportion of American voters who favor congressional term limits is 64 percent with a difference of 3% for small sample size.

Margin of error= z *σ/√n→

This indicates that as the sample size decreases the margin of error increases and vice versa.

Could someone PLEASE just HELP me with this question.

agasfer [191]

Answer

$\frac{7}{37}$

Detailed Explanation

To simply answer this, since .189 has three digits we are going to be inserting 999 as the denominator since it is a repeating decimal.

$\frac{189}{999}$

We could simplify the answer!

$\frac{189}{999}$

Therefore, the answer would simply be $\frac{7}{37}$

$\frac{7}{37}$

Always Remember

In the future, always remember whenever you have a three digit decimal and the problem asks you to convert it into a fraction, you should always insert 1000 as the denominator (the numerator is basically the decimal without the decimal point) and simplify if necessary.
