Answer:

the mean of her survey has increased in the second set of data (by 2)

Step-by-step explanation:

if no one has been given homework since the last time she surveyed, the number of days of not being given math homework will have increased by two for each student, as she surveyed again two days later and nothing changed. therefore overall, everyone's data increases by two therefore raising the mean of her second set by 2

hope this helps :)
