3)
Correlation Coefficient is calculated using the given below formulae:
Hence, r = 0.9998
The value indicates very strong linear correlation between the two variables ie when one variable increases, the other also increases and vice versa.
4)
Regression Output
Regression Equation
River Discharge = 5,420.10 * Gage Height - 24,635.66
When Gage Height = 17.55,
River Discharge = 5,420.10 * 17.55 - 24,635.66 = 70,487.09 cubic feet/second.
5)
From scatterplot 1 we conclude that Gage Height decreased over time.
From scatterplot 2 we can also conclude that River Discharge decreased over time.
From Scatterplot 3, we can conclude that Gage Height and River Discharge are very strongly corelated.
