Suppose a new production method will be implemented if a hypothesis test supports the conclusion that the new method reduces the mean operating cost per hour.

a$.$ State the appropriate null and alternative hypotheses if the mean cost for the current production method is $$235$ per hour.

$H_0$:$-$ Select your answer $-235$

$H_a$:$-$ Select your answer $-AA235$

b$.$ What is the Type I error in this situation?

Claiming $,235$ when the new method $-$ Select your answeh $-$ lower costs.

What are the consequences of making this error?

A mistake could be implementing the method when it $|$ help.

c$.$ What is the Type II error in this situation?

Claiming $$

$235$ when the new method J$.$ lower costs.

What are the consequences of making this error?

This could lead to not implementing a method that lower costs.
