Question

HELP ASAP PLEASE MY DAD AND MOM ARE BOTH VERY MAD AT ME RIGNT NOW SO PLEASE HURRY UP

The line plot represents data collected from a used bookstore.


A horizontal line labeled Cost in Dollars starts at 1 with tick marks every one unit up to 8. There are two dots above 2 and 6. There are three dots above 3 and 5. There are four dots above 4. The graph is titled Cost of Used Books.


Which of the following describes the spread and distribution of the data represented?


The data is almost symmetric, with a range of 9. This might happen because the bookstore offers a sale price for all books over $6.

The data is skewed, with a range of 9. This might happen because the bookstore gives away a free tote bag when you buy a book over $7.

The data is bimodal, with a range of 4. This might happen because the bookstore sells most books for either $3 or $6.

The data is symmetric, with a range of 4. This might happen because the most popular price of a book at this store is $4.

Answer 1

Explanation:

The answer is the last one - symmetric with a range of 4. The data is symmetric which means it peaks in the middle and comes down evenly on both sides.

The range is 4 - Max - Min = 6-2 =4

It is not bimodal. Mode is the most commonly occuring value.

which is 4. More books are sold for $4 than any other cost.

To be bimodal - you would need two data values both representing the most commonly occurring value. You would have 2 peaks that were even in height.

Hope this helps.
