1. what can be deduced from the scatter plot create for the previous problem?

a.) joshs bowling scores are staying about the same.
b.) joshs bowling scores are getting worse overall.
c.) joshs bowling scores are improving overall.
d.) none of the above can be determined from the scatter plot.

Explanation:

Step1: Analyze the data trend

As the \(x -\)value (let's assume it represents something like the number of games or attempts) increases from \(8\) to \(9\) to \(10\), the \(y -\)value (bowling score) increases from \(180\) to \(190\) to \(200\).

Step2: Recall correlation definitions

• Positive correlation: When one variable increases, the other variable also increases.
• Negative correlation: When one variable increases, the other variable decreases.
• No correlation: No consistent relationship between the variables.

Since the bowling score (dependent variable) increases as the other variable (independent variable, say game number) increases, there is a positive - trend relationship.

Answer:

C. Josh’s bowling scores are improving overall.
