Unknown Mean and Variance

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

For One Unknown

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

For Two Unknowns

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