Test the Claim That the Samples Come from Populations with the Same

question 118

Essay

Test the claim that the samples come from populations with the same mean. Assume that the_
populations are normally distributed with the same variance. $$\begin{array} { c c c } \text { Exercise A } & \text { Exercise B } & \text { Exercise } \mathbf { C } \\\hline 2.5 & 5.8 & 4.3 \\8.8 & 4.9 & 6.2 \\7.3 & 1.1 & 5.8 \\9.8 & 7.8 & 8.1 \\5.1 & 1.2 & 7.9\end{array}$$ At the 1% significance level, does it appear that a difference exists in the true mean weight
loss produced by the three exercise programs?

Definitions:

Inductive Reactance

The impedance offered by inductors in a circuit to the flow of alternating current, determined by the frequency of the current and the inductance of the inductor.

Series Circuit

A circuit that contains only one path for current flow.

Total Resistance

The combined resistance of all resistors in a circuit, which determines the amount of current flowing through the circuit.

Wattless Power

See reactive power.
