$ \mathrm{H}_{\mathrm{a}}: \mu< $ Manufacturer's claims

B) $ \mathrm{H}_{0}: \mu= $ Manufacturer's claims 
$ \mathrm{H}_{\mathrm{a}}: \mu \neq $ Manufacturer's claims

C) $ \mathrm{H}_{0}: \mu= $ Manufacturer's claims
$ \mathrm{H}_{\mathrm{a}}: \mu> $ Manufacturer's claims

D) $ \mathrm{H}_{0}: \mu \neq $ Manufacturer's claims 
$ \mathrm{H}_{\mathrm{a}}: \mu= $ Manufacturer's claims

Quizplus · Accepted Answer

The null hypothesis ($ \mathrm{H}_{0} $) states that the mean running time is equal to the manufacturer's claims, while the alternative hypothesis ($ \mathrm{H}_{a} $) suggests it is not equal, indicating a two-tailed test.
