(Non-Directional Hypothesis)
Illustrative Example 2:
(Directional Alternative Hypothesis)
Illustrative Example 3:
(Directional Alternative Hypothesis)
Private universities' mean tuition cost is
The mean number of years Filipinos
work before retiring is 34.
more than P110,000 per year.
The average TV viewing time of all five-
year old children is less than 3 hours
daily.
Null Hypothesis:
H: The mean number of years Filipinos
work before retiring is 34.
H: μ= 34
Alternative Hypothesis:
H.: The mean number of years Filipinos
work before retiring is not 34.
H.i µ # 34
Null Hypothesis:
H,: The mean tuition for private
universities cost less than or equal to
P110,000 per year.
H: μ Pl 10,00
Alternative Hypothesis:
Hạ: The mean tuition for private
universities cost more than Pl10,000
Null Hypothesis:
H,: The average TV viewing time of all
five-year old children is greater
than or equal to 3 hours daily.
H: µ23
Alternative Hypothesis:
Hạ: The average TV viewing time
of all five-year old children is less
than 3 hours daily.
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.
