SCENARIO 9-10 A Manufacturer Produces Light Bulbs That Have a Mean Life

question 42

Short Answer

SCENARIO 9-10
A manufacturer produces light bulbs that have a mean life of at least 500 hours when the production process is working properly.Based on past experience,the population standard deviation is 50 hours and the light bulb life is normally distributed.The operations manager stops the production process if there is evidence that the population mean light bulb life is below 500 hours.
-Referring to Scenario 9-10,if you select a sample of 100 light bulbs and are willing to have a level of significance of 0.10,the probability of a Type I error is _____if the population mean bulb life is 510 hours.

Definitions:

Depolarization

A reduction in the difference in electric charge across a cell membrane, leading to the activation of nerve or muscle cells.

Reuptake

A process by which neurotransmitters are absorbed back into a neuron after having been released into a synapse, thus terminating the transmission of signals.

Excitatory PSPs

Excitatory postsynaptic potentials are increases in potential that bring a neuron closer to the threshold for firing, facilitating the transmission of signals.

Inhibitory PSPs

Post-synaptic potentials that make a post-synaptic neuron less likely to generate an action potential.
