Answer 1

Step-by-step explanation:

Parameters

1. Population mean = μ = ( Σ Xi ) / N
2. Population mean = μ = ( Σ Xi ) / NPopulation standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ]
3. Population mean = μ = ( Σ Xi ) / NPopulation standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ]Population variance = σ2 = Σ ( Xi - μ )2 / N
4. Population mean = μ = ( Σ Xi ) / NPopulation standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ]Population variance = σ2 = Σ ( Xi - μ )2 / NVariance of population proportion = σP2 = PQ / n
5. Population mean = μ = ( Σ Xi ) / NPopulation standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ]Population variance = σ2 = Σ ( Xi - μ )2 / NVariance of population proportion = σP2 = PQ / nStandardized score = Z = (X - μ) / σ
6. Population mean = μ = ( Σ Xi ) / NPopulation standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ]Population variance = σ2 = Σ ( Xi - μ )2 / NVariance of population proportion = σP2 = PQ / nStandardized score = Z = (X - μ) / σPopulation correlation coefficient = ρ = [ 1 / N ] * Σ { [ (Xi - μX) / σx ] * [ (Yi - μY) / σy ] }
