Determine the standardized test statistic
WebDetermine the standardized test statistic, z, to test the claim about the population proportion p ≥ 0.132 given n=48 and p=0.11 Use a=0.05 -1.645 -0.124 -0.568 -0.45 This … WebX and X̅ are standardised slightly differently. In both cases, the denominator is the square root of the variance, like so: For X, Z = (X-μ) / σ. For X̅, Z = (X̅ - μ) / (σ / √n) This fits with what we know about the central limit theorem. For X, the variance is σ².
