Simplifying 7 + -2(2 + 3x) = 27 7 + (2 * -2 + 3x * -2) = 27 7 + (-4 + -6x) = 27 Combine like terms: 7 + -4 = 3 3 + -6x = 27 Solving 3 + -6x = 27 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -6x = 27 + -3 Combine like terms: 3 + -3 = 0 0 + -6x = 27 + -3 -6x = 27 + -3 Combine like terms: 27 + -3 = 24 -6x = 24 Divide each side by '-6'. x = -4 Simplifying x = -4

For a population with an unknown distribution, the form of the sampling distribution of the sample mean is _____.a. exactly norm

maxonik [38]

Answer:

Approximately normal for large sample sizes

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

The distribution is unknown, so the sampling distribution will only be approximately normal when n is at least 30.

So the correct answer should be:

Approximately normal for large sample sizes
