Question

When researching the population of hammerhead sharks found in different areas of the Atlantic Ocean, the range is calculated to be 5,000. Which piece of information would NOT be necessary in order to calculate the range for this data?

A) The average number of sharks was 7,550.
B) The smallest population of sharks found was 5,000.
C) The highest population of sharks found was 10,000.
D) No place was found to have a higher shark population greater that 10,000.

Answer 1

A is correct.  To find range, subtract the minimum from the maximum (Max - Min).  B describes the minimum, while C and D both describe the maximum.

Answer 2

The correct answer is A) The average number of sharks was 7,550.

Step-by-step explanation:

The average number do not play any role in calculating the range of particular data. The range of particular data can be calculated when we have the lowest number of that data and the highest number of the data.

Then to find out the range lowest number is subtracted with the highest number of the data. Here the range is calculated to be 5,000 so the highest population can be 10,000 and lowest population can be 5,000. Therefore after subtracting 5,000 with 10,000 we get a range of 5,000.

So, the correct answer is A) The average number of sharks was 7,550.
