Question 1
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.
Book Mean Median Mean absolute deviation
English 48.9 52 9.2
History 40.5 44 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
Question 2
Abel uses a probability simulator to roll a six-sided number cube 100 times and to flip a coin 100 times. The results of the experiment are shown below:
Number on the Cube Number of Times Rolled
1 12
2 18
3 30
4 22
5 10
6 8
Heads Tails
34 66
Using Abel's simulation, what is the probability of rolling a 2 on the number cube and the coin landing on tails?
A fraction 84 over 10,000
B fraction 1,188 over 10,000
C fraction 18 over 100
D fraction 66 over 100
Question 3
The dot plots below show the age of some dance students and some yoga students:
(picture is on the bottom)
Based on visual inspection of the dot plots, which group of students appears to have the larger average age?
A The yoga students
B The dance students
C Both groups are similar.
D Not enough information is available to draw a conclusion.
