In a physics class Alex and Mike were performing a hypothesis test concerning the mean amount of static electricity in a capacitor. Both students computed the same test statistic but Alex's result was to reject the null hypothesis while Mike's result was not to reject the null hypothesis. Which of the following is NOT a possible explanantion for why the students had different conclusions?
Alex was testing at the 0.05 significance level and Mike was testing at the 0.01 significance level.
Alex was performing a one-tail test and Mike was performing a two-tail test.
Alex considered the test statistic to be z while Mike considered the test statistic to be t.
Alex performed an upper-tail test while Mike performed a lower-tail test.
Alex computed the p-value of the test statistic while Mike compared the test statistic to the corresponding critical value from the t-Table of Critical Values.
