algol13

The quantity of water left in the tank as described in the task content is; 111 l 220ml.

<h3>What is the amount of water left in the tank?</h3>

The tank described in the task content initially contains 200 liters, in which case, 1 liter corresponds to 1000ml.

Hence, when 88l 580ml was used, the remaining quantity of water is; 200l - (88l 580ml) = 111 l 420ml.

And finally, since 200 ml leaked, the quantity of water left is; 111l 220ml.

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.
