1. Determine the regression equation
2. Complete the ANOVA table.

Answer 1

Tgwre is no attached ANOVA chart.

Answer:

y = 0.762x + 1.72

Explanation:

Given the data above , the regression model obtained using a Pearson linear regression calculator is :

y = 0.762x + 1.72

The regression equation cloud be interpreted as follows :

Slope, which is the increase in the value of y per unit increase in x = 0.762

The intercwpt, which is the value of x when y = 0 is 1.72

x = amount of money spent in fireworks for 4th July

y = Attendance at the October fall festival.
