answer:
the mean for this is 27
step-by-step explanation:
all you have to do is add up all of the times
15, 18, 20, 22, 28, 37, 49
which would have given you
189
then you divide that number by how much times were written down
7 would be that number so
189/7 = 27
and this is what it is written in one equation
(15+18+20+22+28+37+49)/7
hope this helps you! :)
