Suppose the distribution of the daily calcium intake of americans is left skewed with a mean of 800 mg and a standard deviation of 16 mg. what can we say about the sampling distribution of distribution x?

a. the mean of the sampling distribution of x is 800.

b. the standard deviation of the sampling distribution of x is 16.

c. the value of every sample mean is 800the sampling distribution of x will be approximately normal regardless of sample size.

a. The mean of the sampling distribution of X is 800.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size of the sampling distribution can be approximated to a normal distribution with mean and standard deviation .

So, the correct answer is

a. The mean of the sampling distribution of X is 800.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range
