Type I Error: Efficiency Rating of a Boiler

APSTAT-9WEDKC

A new boiler is being advertised to have an efficiency rate of $91\%$. The company's competitor believes the new boiler is producing an efficiency rate of less than $91\%$. The company's competitor designs an experiment by randomly selecting 100 of the new boilers to test their efficiency rate.

Under which of the following conditions would a Type I error be committed?

A

The competitor's company concludes that the new boiler's efficiency rate is less than $91\%$ when it is actually $91\%$.

B

The competitor's company concludes that the new boiler's efficiency rate is not less than $91\%$ when it is actually less than $91\%$.

C

The competitor's company concludes that the new boiler's efficiency rate is $91\%$ when it is actually $91\%$.

D

The competitor's company concludes that the new boiler's efficiency rate is less than $91\%$ when it is really less than $91\%$.

E

A type I error cannot be committed in this situation.
