What you should expect in the final Test a claim about a proportion, or a mean with known or unknown standard deviation σ or a standard deviation σ (equivalently the variance). Claim and its opposite in symbolic forms. H 0 and H 1 . Requirements and test statistics Decision about H 0 and conclusion about the claim. You may be given a sample of two paired data values, and ask you to test if there is a correlation between two variables. Testing if there is a linear correlation between two variables: H 0 : ρ = 0 (The is no linear correlation). H 1 : ρ 6= 0 (There is a linear correlation). Find the linear correlation coefficient r .
