Create a dot plot of the data shown below. 20, 21, 21, 25, 20, 23, 27, 23, 24, 25, 26, 24, 23, 22, 24 which measure of center would best describe a typical value of the data set? why?

Median; 23

Step-by-step explanation:

We have been given a data and we need to find the center of the given data for that we will find median of the data

For median we have two formulas

Case 1: when n is odd

Case 2: when n is even

n is the number of observations given

Here, we have 15 observations

Then we will use the formula for when n is odd

After substituting value of n=15 in we will get

That means

And our

Hence, 23 is the center that would best describe a typical value of data set given.

the first dot plot best represents the data

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
