Greta wants to know what the average number of pages is in the books she’s read over the last year. She creates a simple random sample of 10 books she has read in the last year and records their page numbers below: Summarize the average number of pages, and the standard deviation of the data set below. In addition to showing your work, make sure to write a final sentence summarizing both values.

Solutions
Expert Solution
Total pages of 10 books = 307 + 385 + 412 +204 +99 +252 +110 +365 + 188 + 203
= 2525
1) Average number of pages in the book greta reads is (
)
Total pages of 10 books / total number of
books
2) Standard deviation of the given data set is
in above eqaution 
--------------------- from 1)
Average number of pages in the book greta reads is 252.5 and its
standard deviation is 139.5272 .
