Homework Help: Statics

Posted by Heather on Sunday, December 2, 2012 at 10:44am.

You wish to test whether or not a coin is fair, so you toss it 400 times and obtain 220 heads. Test the null hypothesis that the coin is fair and balanced against the alternative that it is not fair and balanced. Use the 1% significance level. Be sure to identify the null and alternative hypotheses, identify the appropriate distribution and indicate the tail(s) for the critical region, identify and calculate the test statistic, determine the P-value, make a decision and state a conclusion.
