Question

dataset the data show the number of wins a soccer team has and the total number of points the team scored. find the equation of the regression line. find the y-value for the specified x-value. remember that no regression should be done when r is not significant. use the p-value method and tables. wins | 8 15 7 19 18 11 14 points | 48 53 51 61 57 49 51 send data to excel part: 0 / 8 part 1 of 8 (a) draw a scatter plot.

Explanation:

Step1: Identify Variables

Let \( x \) be the number of wins (values: 8, 15, 7, 19, 18, 11, 14) and \( y \) be the points (values: 48, 53, 51, 61, 57, 49, 51).

Step2: Plot Points

For each \( (x, y) \) pair:

• \( (8, 48) \): Locate \( x = 8 \) on x - axis, \( y = 48 \) on y - axis, mark the point.
• \( (15, 53) \): Locate \( x = 15 \), \( y = 53 \), mark.
• \( (7, 51) \): Locate \( x = 7 \), \( y = 51 \), mark.
• \( (19, 61) \): Locate \( x = 19 \), \( y = 61 \), mark.
• \( (18, 57) \): Locate \( x = 18 \), \( y = 57 \), mark.
• \( (11, 49) \): Locate \( x = 11 \), \( y = 49 \), mark.
• \( (14, 51) \): Locate \( x = 14 \), \( y = 51 \), mark.

(Note: Since this is a manual scatter - plot drawing instruction, the actual plotting is done by marking these points on the given coordinate system where the x - axis represents 'Wins' and the y - axis represents 'Points'.)

Answer:

The scatter plot is drawn by plotting the points \((8, 48)\), \((15, 53)\), \((7, 51)\), \((19, 61)\), \((18, 57)\), \((11, 49)\), \((14, 51)\) on the coordinate plane with the x - axis as the number of wins and the y - axis as the number of points.
