Answer:
Step 1:
a.) 16 pets in total (1 + 0 + 2 + 0 + 3 + 8 + 0 + 2)
b.) the mean is 2 (16 is the total number of pets, divide that by 8 which is the total number of students asked, 16/8 = 2)
Step 2:
a.) 0, 0, 0, 1, 2, 2, 3, 8 (zero, one, two, three, four, five, six, seven, eight.)
b.) 0 and 3 are the middle numbers (center.)
c.) 3/2 = 1.5 (0+3 = 3 divided by 2 = 1.5)
Step 3:
- most of the students did not have any pets, so the mode would be 0 (it is zero because zero appears in the set of numbers 3 times. More than any other number).
Step 4:
They should use the mean of the amount of pets the students have; this is because the mean is the average amount of pets counting everyone in class—regardless on if there were zeros in the list.
