Resumen del Recurso

Diapositiva 1

    Unknown Mean and Variance
    X~N(μ, σ^2)Let Z=X-μ/σNB: Table 3 contains probabilities        Table 4 contains Z-values for selected probabilities

Diapositiva 2

    For One Unknown
    Use Z=X-μ/σ with available valuesFind Q-value that gives probabilityLet X-μ/σ = Q-value

Diapositiva 3

    For Two Unknowns
    Use the same method as for One UnknownWIll end up being Simultaneous Equations that need to be solved
