Document Summary

In a rather counter-intuitive way we are testing the null hypothesis (in this case, the hypothesis that there is no difference): h. 0: state the alternative hypothesis. (in this case, the alternative hypothesis is that there is a difference): h. Calculate the z-score by plugging the values into the formula: (answer: 2. 96) = reject null at 99% confidence. Use the resulting z-score value to determine whether to reject the null hypothesis. If our cut-off is 0. 05 (95% confidence level) Do we reject the null hypothesis of no difference. If our cut off is . 01 (99% confidence level) Reject null hypothesis when zscore lies outside of +/- 2 with 95% confidence. When zscore outside of +/- 2. 6, we reject null hypothesis at 99% confidence level. When zscore of +/-2-2. 59 = 95% confident level. Zscore of +/-2. 6 or more = 99% confidence level.
