Answer:

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 health care varies in each state, so that affects the life longevity and also different imcomes affect the care people resceive. 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: 75 (Need to round up for this)

Greatest: 83 (Need to round up)

Q1: 90.2 (Got this by adding the two numbers of the upper half of data and dividing by 2)

Median/mean: 86.2 (Average of the data)

Q3: 85 (Rounded. Got this by adding the two numbers of the middle half of data and dividing by 2)

Answer:

A: 75

B: 86.2

C: 90.2

D: 85

E: 83

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.
