Essay

Assume that a simple random sample has been selected from a normally distributed population. Find the test statistic, P-value, critical value(s), and state the final conclusion.
-Test the claim that the mean lifetime of car engines of a particular type is greater than 220,000 miles. Sample data are summarized as $n = 23 , \bar { x } = 226,450$ miles, and $s = 11,500$ miles. Use a significance level of $\alpha = 0.01$ .

Definitions:

Capacitive Reactance

Capacitive reactance is the measure of opposition that a capacitor offers to AC (alternating current), and it decreases with an increase in the frequency of the electric signal.

Resistive Current

The current that flows through a circuit with only resistive elements, directly proportional to the voltage across and inversely proportional to the resistance.

RC Parallel Circuit

An electrical circuit that consists only of a resistor (R) and a capacitor (C) connected in parallel, affecting the overall impedance and phase angle.

RC Parallel Circuit

A type of electrical circuit where resistor(s) and capacitor(s) are connected in parallel, affecting the charging and discharging rate of the capacitor.
