Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
As the value of r increases, what happens to the value of F?
A
F increases
B
F decreases
C
F never changes, q does
D
Cannot know from the information
Explanation: 

Detailed explanation-1: -Thus resonant frequency of the circuit increases if the value of C decreases.

Detailed explanation-2: -From the above equation, the resonant frequency of the series RLC circuit is inversely proportional to the square root of the capacitance. By the above equation, the value of the capacitance $C$ in a series RLC circuit is decreased, then the resonant frequency in a series RLC circuit is increased.

Detailed explanation-3: -Interpreting the Overall F-test of Significance Compare the p-value for the F-test to your significance level. If the p-value is less than the significance level, your sample data provide sufficient evidence to conclude that your regression model fits the data better than the model with no independent variables.
