4 0

Answer:

Therefore, x is 1 and 2.

Step-by-step explanation:

As you plot both equations on the same graph, you will get something like this, shown in the graph.

Then, you have to find the x solutions where they intersect.

So, both equations intersect at x = 1 and 2.

Suppose your marketing colleague used a known population mean and standard deviation to compute the standard error as 52.4 for s

Brilliant_brown [7]

Answer:

The standard error for the new sample size is of 23.4.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes 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.

Interpretation:

From this, we can gather that the standard error is inversely proportional to the square root of the sample size, that is, for example, if the sample size is multiplied by 4, the standard error is divided by the square root of 4, which is 2.

Standard error of 52.4, sample size multiplied by 5. What is the standard error for the new sample size?

The standard error of 52.4 divided by the square root of 5. So

$s = \frac{52.4}{\sqrt{5}} = 23.4$

The standard error for the new sample size is of 23.4.

Dave had 421 blocks Tom had 384 blocks and Jane had 656 blocks how many more blocks do Dave and Jane have them Tom

quester [9]

Answer: 149

Step-by-step explanation:

Well first, add the amount of Dave and Tom's blocks together. 421+384=805. Then subtract Jane's amount from Dave and Tom's. 805-656. That should get you your answer. 149.
