Answer:
3. The distributions do not overlap for any values. None.
4. $28.14
5. B.
Step-by-step explanation:
3. Compare both charts and see if any of the values are exactly same for the similarly labelled graphs. None of the data values coincide when compared to their counterpart in the other class.
4. Find the average sales of the first shop - aka Coffees R' Us.
(36 + 41 + 63 + 42 + 48 + 50 + 53) / 7 = $47.57
Find the average sales of the second shop.
(70 + 73 + 78 + 80 + 75 + 85 + 69) / 7 = $75.71
Now the sales difference is just the difference between the two:
$75.71 - $47.57 = $28.14
5. B. Because you can infer from the graphs that, on average (which refers to mean), the scores have increased.
