Please help explain!!

Answer 1

Answer:

The box and whisker plot is shown in the figure attached. Further information on parameters is as follows:

Population size: 16

Median: 121794

Minimum: 198

Maximum: 284332

First quartile: 34421.25

Third quartile: 178448.25

Interquartile Range: 144027

Answer 2

Answer:

See below

Step-by-step explanation:

Think: They want us to make a box-o-gram (histogram and box-whisker-plot combo).

Identify: They gave us the information we need and we know that Alaska is the largest state. We will make the box-o-gram after ordering the data appropriately.

Do: After ordering the numbers from least to greatest, we make calculations for the medians and mean. Here are the answers:

Least: 198

Greatest: 284,332

Q1: 30,123 (Got this by adding the two numbers of the upper half of data and dividing by 2)

Median/mean: 100,233.2 (Average of the data)

Q3: 202,112.3 (Rounded. Got this by adding the two numbers of the middle half of data and dividing by 2)

Answer:

A: 198

B: 30,123

C: 100,233.2

D: 202,112.3

E: 284,332

Yes, this makes sense since the data on the box-o-gram fall within the data given in the chart at the top of the worksheet.
