TEST STATISTICS, CRITICAL VALUE AND P-VALUE FOR HYPOTHESIS TESTING OF TWO SAMPLES (CH11) TYPE OF TEST MEAN (μ) USING t-DISTRIBUTION USING INDEPENDENT SAMPLES MEAN (μ) USING t-DISTRIBUTION USING DEPENDENT SAMPLES NOTES All 1. Samples are independent when they can not be paired. 2. If testing that μ1=μ2 then μ1-μ2=0. 1. Samples are dependent when they can be paired. 2. Use ordered pairs to calculate the mean and std. dev. of the difference d ( d & d s ) 3. Testing 0 d μ = .
