Hi there!

Okay, so this is pretty simple. Just follow my instructions!

1/4a = 3

4 * (1/4a) = (4) * (3)
Use a calculator to solve this, remembering PEMDAS.

a = 12

Your final answer is a = 12. When in doubt replace "a" with the new given variable number, which is twelve.

Hope this helps!

And by the way, I love the attached file. It's really cute! :P

Answer:

31% of the surveyed voters said they would vote for Brown.

Step-by-step explanation:

A sample statistic is a a statistical measure computed from a sample taken from the population. The sample statistic is used to estimate the unknown value of the population parameter.

For example, sample mean (\bar x) is used estimate the population mean (\mu), sample proportion (\hat p) is used to estimate the population proportion (p).

A sample of size <em>n</em> = 350 registered voters are selected.

Of these 350 voters 108 said they would vote for Brown, 217 said they would vote for Feliz, and 25  were undecided.

The sample proportion of voters who would vote for Brown is:

\hat p=\frac{108}{350}= 0.3086\approx0.31

Thus, the sample statistic for the percentage of voters surveyed who said they would vote for Brown is 31%.

According to the sample proportion the estimated percentage of voters who would vote for Brown is 31%. This implies that Brown might loose the election.
