The correct answer is:
The correct scatter plot is attached.
There appears to be a negative correlation between a person's age and the amount they spend on a night out.
Explanation:
Age will be the independent variable, along the x-axis, and the cost of a night out will be the dependent variable, along the y-axis.
The ages range from a low of 20 to a high of 45. We will start our graph at 0 and use a scale of 5s along the x-axis, going to 45.
The amounts for a night out range from a low of 38 to a high of 58. We will start our graph at 0 and use a scale of 5s along the x-axis, going to 60.
We then plot each point as a coordinate of (age, amount spent).
Once we get the graph plotted, we see there is a negative trend in the data. As the age increases, the amount spent out decreases.
