QUESTION 5 A one-tail, one-sample hypothesis test is more powerful than a two-tail, one-sample hypothesis test is less powerful than a two-tail, one-sample hypothesis test requires a skewed population lowers random sampling error All of the choices aboveQUESTION 2 How are one-sample hypothesis tests different from confidence intervals? One-sample hypothesis tests construct intervals and partial intervals around benchmarks instead of intervals around estimators. One-sample hypothesis tests are not different from confidence intervals. One-sample hypothesis tests provide less information about random sampling error. All of the choices above None of the choices
