6.103 More than one test.

A -value based on a single test is misleading if you perform several tests. The Bonferroni procedure gives a significance level for several tests together. Level then means that if all the null hypotheses are true, the probability is that any of the tests rejects its null hypothesis.

If you perform two tests and want to use the significance level, Bonferroni says to require a -value of to declare either one of the tests signifcant. In general, if you perform tests and want protection at level , use as your cutoff for statistical significance for each test.

You perform six tests and obtain individual -values of . Which of these are statistically signifcant using the Bonferroni procedure with ?
