A health food store has launched a new pack of vitamins for children. The store records the number of packs ordered by a random sample of 100 online customers and the number of packs ordered by a random sample of 100 walk-in customers. Two dot plots are shown one below the other. The title for the top dot plot is Online Customers and the title for the bottom plot is Walk In Customers. Below the line for each dot plot is written Number of Packs. There are markings from 2 to 6 on each line at intervals of one. For the top line there are 0, 0, 1, 4, 5 dots respectively for marks from 2 to 6. For the bottom line there are 3, 6, 1, 0, 0 dots respectively for marks from 2 to 6. On the right side, towards the middle of the two plots is shown a dot symbol equal to 10 customers. Which of the following inferences can be drawn about the buying pattern of the online customers versus that of the walk-in customers?

Can you screenshot the whole problem with the dot plots and choices?

briannamilcic:

So we need to find the average of both dot plots For online customers [4+4(5) + 5(6)] divided by 10 For walk in customers [ 3(2) + 6(3) +4] divided by 10 After you find the average, round it the nearest whole number, and you'll get your answer

briannamilcic:

ok can i put what i get in to see if i am right

snowflake0531:

Tell me what you get as the 2 averages

briannamilcic:

Yes which is 5.4, which rounds to 5

briannamilcic:

snowflake0531:
