In Exercise 8 113 on page 335 we introduced one sided one mean
In Exercise 8.113 on page 335, we introduced onesided onemean tintervals. The following relationship holds between hypothesis tests and confidence intervals for onemean tprocedures: For a lefttailed hypothesis test at the significance level α, the null hypothesis
H0: μ = μ0 will be rejected in favor of the alternative hypothesis
Ha: μ < μ0 if and only if μ0 is greater than the (1 − α)level upper confidence bound for μ.
In each case, illustrate the preceding relationship by obtaining the appropriate upper confidence bound and comparing the result to the conclusion of the hypothesis test in the specified exercise.
