Okay, my prior answer got deleted for no work, apparently.
I'll re-post it though.

That word problem translates to:
8n -4=0 \\ +4 \\  \\ 8n=4 \\ /8 \\  \\ n=1/2

To estimate the percentage of a state's voters who support the current
Lady bird [3.3K]

Using the Central Limit Theorem, the percentage that is expected to be the closest to the actual percentage is:

A. The Tribune, at 68%.

<h3>What does the Central Limit Theorem state?</h3>

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean \mu = p and standard error s = \sqrt{\frac{p(1 - p)}{n}}, as long as np \geq 10 and n(1 - p) \geq 10.

From this, a larger sample size leads to a smaller error estimate. Since the Tribune had the largest sample size, option A is correct.

ozzi
The solution is completely correct, as putting 5 or 0 in the formula again will make it true.

|2(0)-5|=5
|-5|=5
5=5

|2(5)-5|=5
|10-5|=5
5=5

Ms. Brown predicted that 25% of the days in January would have temperatures below 45°F. How many days does she predict will have
Dmitriy789 [7]

The answer is 7.75. Since there can not be 7.75 days, you can round that to 8 and say that it's almost 8 days. Hope this helps!
