1000 significance tests are performed using alpha = .05. Assumimg that all null hypotheses are true, about how many of the test results would you expect to be statistically significant?

  • statistics -

    About .05 or 5% of 1000 = 50. P = .05 indicates that the probability of the observed events would occur by chance 5 times in 100.

    I hope this helps. Thanks for asking.
