Document Summary

We need a point estimate plus or minus our margin of error. Alternative hypothesis is related to region of rejection. Say/relate confidence to what you were analyzing. Explanation section 2: calculate confidence interval: you can say and relate it to what you were analyzing. Mean of the post communist data, therefore we can say with 95% of confidence that population parameter is the mean of the score of citizens of communist states is somewhere between . Probability value into standardized value called a t score. Stick it into chi- function etc fifth step, you take your unstandardized test statistic into a standardized value. X bar, subtract off the hypothesized value. Universal standardized score (mean of standardized score): mew= 0. Value and get it there, therefore, the form of the hypothesized test is: we do not reject null hypothesis. B/c we know our alpha score is 0. 5 we are looking for probability score of less than 0. 5.
