Esther wants to know if the number of words on a page in her language arts book is generally more than the number of words on a page in her social studies book. she takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book. book mean median mean absolute deviation language arts 78.5 60 14.2 social studies 68.7 65 9.8 she claims that because the mean number of words on each page of the language arts book is greater than the mean number of words on each page of the social studies book, the language arts book has more words per page. based on the data, is this a valid inference? yes, because there is a lot of variability in the language arts book data no, because there is a lot of variability in the language arts book data yes, because the mean is larger in the language arts book no, because the mean is larger in the social studies book

So the correct answer is "No, because there is a lot of variability in the language arts book data."

Step-by-step explanation: I'm doing this test right now on FLVS and i used this answer for help and i got a 100 so this answer is VERY correct.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
