Ono, Masatoshi TTh: 10:30 ~ 12:00 Basic Statistic 7 steps of hypothesis testing Step 1: State the Null Hypothesis.
H0:μ1=μ2=⋯=μk Step 2: State the Alternative Hypothesis.
HA: treatment level means not all equal Step 3: Set α.
In Reality Decision
H0 is TRUE
H0 is FALSE
Accept H0
OK
Type II Error β = probability of Type II Error
Reject H0
Type I Error α = probability of Type I Error
OK
Step 4: Collect Data Step 5: Calculate a test statistic. Step 6: Construct Acceptance / Rejection regions.
Step 7: Based on steps 5 and 6, draw a conclusion about H0.
