What is the median of this data set? {10, 15, 12, 6, 2}

Vedmedyk [2.9K]

Hello there!

Median is the middle of the data set.

So, first we have to arrange it into proper numerical order (least to greatest).

2,6,10,12,15

Then, we look for the middle number.

It is 10, therefore 10 would be the median of this data set.

Tomas bought a new sheet of stamps that had 10 thirty-four cent stamps on the page. If he paid with a ten-dollar bill, how much

Alisiya [41]

Answer:

$6.60 dollars

Step-by-step explanation:

He bought 10 34¢ stamps which means it only costed $3.40, because 10x.34=3.40

So in order to find the change, you subtract $10-$3.40, which equals $6.60

Find the margin of error for the given values of c, o, and n.

Alika [10]

Using the z-distribution, it is found that the margin of error is of 0.059.

We are given the standard deviation for the population, hence the <em>z-distribution</em> is used.

<h3>What is the margin of error for a z-confidence interval?</h3>

It is given by:

$M = z\frac{\sigma}{\sqrt{n}}$

In which:

z is the critical value.

$\sigma$ is the population standard deviation.

n is the sample size.

In this problem, the parameters are:

$\sigma = 0.25, n = 49$ .

Confidence level of 0.90, hence, using a z-distribution calculator, the critical value is z = 1.645.

Then:

$M = z\frac{\sigma}{\sqrt{n}}$

$M = 1.645\frac{0.25}{\sqrt{49}}$

$M = 0.059$

The margin of error is of 0.059.
