Answer:
the third one (-2,1)
Step-by-step explanation:
More data can be applied to the frequency distribution table. You can measure the "midpoint" (or "class mark") of each class as: Midpoint = Lower class limit + Upper class limit 2 . . The proportion of the data that falls in that class is the "relative frequency" of each class.
You have to divide 108 with 25.18
about 4.3/1
