Question

I WILL GIVE BRAINLIST**
Lara wants to know if the number of words on a page in her English book is generally more than the number of words on a page in her history book. She takes
a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book
*Mean*
English- 48.9
History 40.5
*Median*
English- 52
History- 44
*Mean absolute deviation*
English- 9.2
History- 1.3

Lara claims that because the mean number of words on each page in the English book is greater than the mean number of words on each page in the history
book, the English book has more words per page. Based on the data is this a valid inference?
A. Yes, because there is a lot of variability in the English book data
B. Yes, because the mean is larger in the English book
C. No, because the mean is larger in the English book
D. No, because there is a lot of variability in the English book data

Answer 1

Answer:

Answer 2

What is a measure of variability?

A measure of variability is the mean absolute variation. It is used to calculate the spread of a data. The greater the  mean absolute variation, the greater the variability. The  mean absolute variation is greater for the english book than for the maths book.
