Hypothesis Test
- What is the sample size?
- n≥30
OR
np≥5
nq≥5
- Use z-distribution to
find your critical value.
- Use z-distribution to
find your critical value.
- n<30
OR
np<5
OR
nq<5
- Do you know the population
standard deviation (σ)?
- Yes. Use
z-distribution to find
your critical value.
- No. Use t-distribution
to find your critical
value.
- Find the value of the test statistic using the appropriate formula
- Compare the critical value and the
test statistic. Does the test statistic
fall in the rejection region?
- Yes. Since the test statistic
falls in the rejection region,
there is sufficient evidence
to reject the null
hypothesis.
- No. Since the test statistic
does not fall in the rejection
region, there is insufficient
evidence to reject the null
hypothesis.
- Yes. Since the test statistic
falls in the rejection region,
there is sufficient evidence
to reject the null
hypothesis.
- Compare alpha (α) and p-value.
Is your p-value less than alpha?
- Yes. Since the p-value is
less than alpha, there is
sufficient evidence to
reject the null
hypothesis.
- No. Since the p-value is
larger than alpha, there
is insufficient evidence
to reject the null
hypothesis.
- Yes. Since the p-value is
less than alpha, there is
sufficient evidence to
reject the null
hypothesis.
