Answer:
x=3, y=5
Step-by-step explanation:
The selected statistical questions are as follows:
<em>A what is the typical amount of rainfall for the month of June in the Galapagos islands</em>
<em />
<em>D how many songs does the class usually listen to each day</em>
<em />
<em>G how long does it typically take for 2nd graders to walk a lap around the track</em>
Statistical questions are known by these two main characteristics:
- they are answered by the collection of data
- there is always variability in the data collected
This means that the data vary. They are not the same data. For example, "How old is Monday?" is not a statistical question because it has one answer.
Thus, statistical questions are not answered by a single number or answer, especially when the correct answer is just one.
