The answer to the first one is yes.

The second one, I would say it is None of the above. If you look, there are 2 x, and if the x are there and we don't know what their value is, they would stick to the 1 and 4, making the answer a number with the variable. Hope this helps!

Aye sir!

Describe how the variability of the distribution changes as the sample size increases. As the sample size increases, the variabi

wolverine [178]

Answer:

As the sample size increases, the variability decreases.

Step-by-step explanation:

Variability is the measure of actual entries from mean. The less the deviations the less would be the variance.

For a sample of size n, we have by central limit theorem the mean of sample follows a normal distribution for random samples of large size.

X bar will have std deviation as $\frac{s}{\sqrt{n} }$

where s is the square root of variance of sample

Thus we find the variability denoted by std deviation is inversely proportion of square root of sample size.

Hence as sample size increases, std error decreases.

As the sample size increases, the variability decreases.

What is the unit value the 3 in 432 ?

lara [203]

Answer:
It represent the tens of the number, therefore, it's unit value is 30

Explanation:
The place value chart is added in the attached image.

Checking this chart, we would find that:
first digit from the right is the units of the number
second digit from the right is the tens of the number
third digit from the right is the hundreds of the number

Comparing this with the nuber given, we would find that the 3 is in the tens position. Therefore, it unit value is 30.

Another way to answer this is by breaking the number given as follows:
432 = 400 + 30 + 2
We can note that the unit value of the 3 is 30

Hope this helps :)
