1.
How many people prefer to drink water?
- From the graph, the height of the "Water" bar is 9.
-
Answer: 9 people prefer to drink water.
2.
How many people were surveyed in total?
- To find the total number of people surveyed, sum the values for all drinks:
\[
\text{Total} = \text{Juice} + \text{Soda} + \text{Milk} + \text{Water} + \text{Lemonade}
\]
\[
\text{Total} = 3 + 8 + 2 + 9 + 4 = 26
\]
-
Answer: 26 people were surveyed in total.
3.
How many more people prefer soda over milk?
- Number of people who prefer soda: 8
- Number of people who prefer milk: 2
- Difference: \( 8 - 2 = 6 \)
-
Answer: 6 more people prefer soda over milk.
4.
Would it be legitimate for this bar graph to have a value that goes in between the y-axis values? Why or why not?
- The y-axis represents the number of people, which must be a whole number since you cannot have a fraction of a person.
- Therefore, it would not be legitimate for the bar graph to have a value that goes in between the y-axis values (e.g., 3.5 people).
-
Answer: No, it would not be legitimate because the number of people must be a whole number.
