Multiple Choice

Consider the following to answer the question(s) below:
A consumer group was interested in comparing the operating time of cordless toothbrushes manufactured by two different companies. They took a random sample of 18 toothbrushes from Company A and 15 from Company B. Each was charged overnight and the number of hours of use before needing to be recharged was recorded. Company A toothbrushes operated for an average of 119.7 hours with a standard deviation of 1.74 hours; Company B toothbrushes operated for an average of 120.6 hours with a standard deviation of 1.72 hours. Do these samples indicate that Company B toothbrushes operate more hours on average than Company A toothbrushes?
-The correct value of the test statistic is

• A) t = -1.489.
• B) t = -4.421.
• C) t = 2.566.
• D) t = 1.488.
• E) t = -2.566.

Definitions:

RC Parallel Circuit

An electrical circuit configuration consisting of resistors (R) and capacitors (C) connected in parallel, affecting current and voltage differently.

R

Symbol commonly used to denote resistance in electrical circuits, measured in ohms (Ω).

Power Factor

The ratio of the real power flowing to the load to the apparent power in the circuit, indicating how effectively electrical power is converted into useful work output.

RC Parallel Circuit

An electrical circuit composed of resistors (R) and capacitors (C) connected in parallel, affecting the total impedance seen by an alternating current (AC) source.
