Do you have a graphing calculator?
This is a final exam review. REVIEW lol and yes I do have a graphing calculator. I know I’m supposed to enter data into a list but I don’t know the numbers..
But this problem doesn’t give out the numbers…just ranges.
Assume the numbers are at the midpoint of the ranges.
@Dr_Lawrence I guess thats the best you can do… but still feels sketchy.
Anyway, if you are doing that, you can covert the table to:
Class…......................... Frequency
21.5…............... 12
29.5….............. 18
37.5…............... 2
If you had 12 people who were 21.5 years old, 18 who were 29.5 years old and 2 who were 37.5 years old, what would you do? (Try from here, see if it helps).
