Short Answer

Create Cumulative Frequency and Relative Frequency Tables
-The local police, using radar, checked the speeds (in mph) of 30 motorists on a rural road. The results are listed below. Construct a relative frequency ogive using six classes. $$\begin{array} { l l l l l l l l l l } 44 & 38 & 41 & 50 & 36 & 36 & 43 & 42 & 49 & 48 \\35 & 40 & 37 & 41 & 43 & 50 & 45 & 45 & 39 & 38 \\50 & 41 & 47 & 36 & 35 & 40 & 42 & 43 & 48 & 33\end{array}$$

Definitions:

D'Arsonval Shunt

A D'Arsonval shunt is a precision resistor used in conjunction with a D'Arsonval meter movement to allow the measurement of high currents by diverting some of the current away from the sensitive galvanometer coil.

Contact Resistance

The resistance to the flow of electricity encountered at the point where two conductive surfaces meet or connect.

Typical Impedance

A standard or average measure of the total resistance faced by current in an electrical circuit, combining both resistive and reactive elements.

Nonconductive

A property of a material that does not allow electric current to flow through it easily.
