Janet and her sister Brenda want to be healthier. Last week, they decided to also track their
steps every day. These boxplots show the results.
Every day Brenda walked more steps than Janet
The median of Janet’s data is greater than the first quartile of Brenda’s data.
Brenda’s step count has more variability than Janet’s
The maximum of Janet’s data is equal to the third quartile of Brenda’s data.
The data distributions show recovery times of athletes before and after the Olympics.
Which statement CORRECTLY explains the summary statistics that should be used to compare
the recovery times?
The distributions are normal, so the mean and standard deviation should be used to
compare the recovery times.
The distributions are skewed, so the mean and standard deviation should be used to
compare the recovery times.
The distributions are normal, so the median and interquartile range should be used to
compare the recovery times.
The distributions are skewed, so the median and interquartile range should be used to
compare the recovery times.
Two groups of students, Group A and Group B, have the shoe sizes shown below. Which
statement about the distributions is true?
Distribution B has a larger mean, but the medians of both distributions are the same.
Distribution B has both a larger mean and a larger median than distribution A.
Distribution B has a smaller mean, but the medians of both distributions are the same.
Distribution B has both a smaller mean and a smaller median than distribution A.
The ages of students in an introductory college class are recorded: 17, 18, 19, 19, 19, 20, 20,
20, 21, 22, and 23. If a new student enrolls who is 67 years old, what is this change’s effect on
the median?
The median increases.
The median decreases.
The median does not change.
There is not enough information to determine what change the new student would have
on the median.

Danny rented 3 movies from RedBox, which he has now had for 10 days. His total cost so far is
$6.90. Which of these equations can be used to determine the amount RedBox charges as a
daily fee?

Emma is saving up to buy an Apple Watch. The one she wants costs $375. Right now, she
has $50 saved in the bank. She has a job helping out at her elderly grandparents’ house and
they pay her $16 per hour. Emma needs to spend x hours working at her grandparents’ house
before she can buy the watch.
Which of the following statements are true? Select THREE that are correct.
The equation 375 = 16x + 50 represents the situation
The equation 375 = 50x + 16 represents the situation
The equation 325 = 16x represents the situation

Mrs. March needs to buy snacks for her daughter's class party. She decides to buy individual
packs of Oreos and Cheez-Its at a local grocery store. The price of the Oreos is $8 for 2 boxes,
and the price of the Cheez-Its is $10 for 2 boxes. Mrs. March ends up buying $20 worth of
snacks. Which equation represents the relationship between the number of boxes of Oreos, x,
and the number of boxes of Cheez-Its, y, that Mrs. March bought at the grocery store?
2x + 2y = 20
8x + 10y = 20
10x + 8y = 20
4x + 5y = 20
