For this case we want to check if the true mean for the depth of groves cut into aluminium by a machine is equal to 1.7 (null hypothesis) and the alternative hypothesis would be the complement different from 1.7. And the best system of hypothesis are:
Null hypothesis:
Alternative hypothesis
Alternative hypothesis [tex]\mu \neq 1.7[/tx]
And the best system of hypothesis are:
