Question

A librarian listed the frequency of books ordered during a recent book fair. The data is shown in the histogram.

A histogram titled Book Sales. The x-axis is labeled Number of Books and has intervals for 0 to 1, 2 to 3, 4 to 5, 6 to 7, 8 to 9, and 10 to 11. The y-axis is labeled Frequency and begins at 0, with tick marks every 2 units up to 10. There is a shaded bar for 0 to 1 that stops at 3, for 2 to 3 that stops at 4, for 4 to 5 that stops at 8, for 6 to 7 that stops at 2, for 8 to 9 that stops at 4, and for 10 to 11 that stops at 8.

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

The data is normal with outliers and shows that most orders were for 5 books.
The data is skewed and shows that there were many large orders for books.
The data is skewed and shows that most orders were for small amounts of books.
The data is bimodal with two peaks and might be because there was a sale for every 5 books that were ordered.

Answer 1

Answer: The histogram shows that most of the bars are skewed to the right, with longer tails on the right side. The largest bar is for the range of 4 to 5 books, indicating that most of the orders were for 4 to 5 books. The other bars have lower frequencies, indicating that fewer orders were made for those ranges of books.

Therefore, the best description of the spread and distribution of the data is that it is skewed and shows that most orders were for small amounts of books. The data is not normal as it is not symmetric and the data is not bimodal as there is no clear evidence of two distinct peaks.

Explanation: Hope This Helps(HTH)

Answer 2

The histogram shows a skewed right distribution, with the majority of orders being for fewer than 5 books. There are a few outliers with larger orders, but they are not significant enough to create a bimodal distribution.

Therefore the answer is "The data is skewed and shows that most orders were for small amounts of books."
