Question

the scatter plot shows the years of experience and the amount charged per hour by each of 25 dog sitters in arizona. also shown is the line of best fit for the data. fill in the blanks below. (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 and amount charged. (c) using the line of best fit, we would predict that a dog sitter with 5 years of experience would charge approximately select

Explanation:

Part (a)

Looking at the scatter plot and the line of best fit, as the years of experience (x - axis) increases, the amount charged per hour (y - axis) also increases. So the amount charged tends to increase.

Since as experience (x) increases, the amount charged (y) also increases, and the points follow a roughly linear pattern (due to the line of best fit), there is a positive correlation between experience and amount charged.

Step1: Analyze the line of best fit

Looking at the graph, when \( x = 5 \) (5 years of experience), we check the y - value (amount charged) on the line of best fit. From the grid, the line of best fit at \( x = 5 \) seems to be around \( y=12 \) (by observing the grid lines: the x - axis is years of experience, y - axis is amount in dollars. At x = 5, the line of best fit is between 10 and 14, and closer to 12).

Answer:

increase
