H: μ<3 per="" year.="" hạ:="" u=""> P110,000 Notes: *We used the “u" since it's an average measurement, otherwise we will be using “p" as symbol for proportion. *We used + for this given example since the given does not require certain direction. Notes: * We used the "" for the null hypothesis, to negate the given statement which is already the alternative hypothesis. * Always pay attention to the given, often it is in the form of null hypothesis, but it can also be in altermative hypothesis form.
