Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science 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
art 68.7 50 15.4
science 54.2 55 7.9
she claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. based on the data, is this a valid inference?
yes, because the mean is larger in the art book
no, because the mean is larger in the art book
yes, because there is a lot of variability in the art book data
no, because there is a lot of variability in the art book data

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or itâs less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graphâs y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
