Question

(a) for these 25 dog sitters, as experience increases, the amount charged tends to select (b) for these 25 dog sitters, there is select correlation between experience (c) using the line of best fit, we would predict that a dog sitter with 9 years of expe select

Explanation:

Step1: Analyze the scatter - plot trend

As we move from left to right (increase in years of experience) on the scatter - plot, the points generally move upwards (increase in amount charged per hour).

Step2: Determine the correlation type

Since the amount charged per hour increases as years of experience increase, there is a positive correlation.

Step3: Predict using the line of best fit

Locate 9 years of experience on the x - axis and then find the corresponding value on the y - axis using the line of best fit. As the line of best fit has a positive slope, the amount charged will increase for a dog - sitter with 9 years of experience.

Answer:

(a) Increase
(b) Positive
(c) Increase
