ernest read in his geography textbook about the 10 cities in the united states with the largest populations. the populations of these cities range from about 1 million to about 8.6 million people. according to ernests textbook, the median population of these cities is about 1.7 million people, and the interquartile range is about 1.2 million people.
what can you conclude from these data and statistics? select all that apply.
the middle 50% of the populations of the 10 largest us cities has a range of about 1.2 million people.
a typical population for one of the 10 largest us cities is about 1.7 million people.
the largest city in the us has about 1 million people.

Explanation:

Step1: Understand inter - quartile range

The inter - quartile range (IQR) represents the middle 50% of the data. Given that the IQR is about 1.2 million people, the middle 50% of the populations of the 10 largest US cities has a range of about 1.2 million people.

Step2: Understand median

The median is the middle value when the data is arranged in ascending or descending order. A median population of about 1.7 million people means a typical population for one of the 10 largest US cities (in the middle - value sense) is about 1.7 million people.

Step3: Analyze population range

The text states that the populations range from about 1 million to about 8.6 million people, so the largest city has about 8.6 million people, not 1 million people.

Answer:

The middle 50% of the populations of the 10 largest US cities has a range of about 1.2 million people.
A typical population for one of the 10 largest US cities is about 1.7 million people.
