1. Based on the output, state the appropriate formal conclusion of the test of the hypotheses

    H0:μ1−μ2=0\displaystyle {H}_{{0}}:\mu_{{1}}-\mu_{{2}}={0}
    Ha:μ1−μ2≠0\displaystyle {H}_{{a}}:\mu_{{1}}-\mu_{{2}}\ne{0}

    and then briefly state the meaning of the conclusion in the context of the question regarding whether there is reason to believe that the average sugar content of all 100% fruit juices sold is any different than the average sugar content of all sodas sold.


  2. Based on the output and the corresponding conclusion, which of the following is a plausible 95% confidence interval for the difference μ1−μ2\displaystyle \mu_{{1}}-\mu_{{2}}?
