How Big Should Sample Size be? Example We have data y=(y 1,…,y N ), where y~N(μ,σ 2 ) We want to test H 0 : μ=θ vs H 1 : μ θ –Chosen significance level=α=0.01.

Decision tree: Example 0 = Not a Saturday, 1 = Saturday Given: rainy, humid, not windy Is it a Saturday? It is a Saturday.
There are two statistical tests for mean: 1) z test – Used for large samples (n ≥ 30) 1) t test – Used for small samples (n < 30)
