hey everyone, i swear i understood this five minutes ago when it was explained to me but now it has escaped again....it always seems to come back to this problem of overlapping confidence intervals - for part b) of the first question, how do we show that 52% is lower than 55% with 95% confidence when the 95% confidence interval for 55% seems to include 52%? or have i done the confidence interval wrong? (i'm sorry if this question has already been asked - i haven't been getting the list's emails until tonight). thanks, zoe _______________________________________________ gov1000-list mailing list gov1000-list(a)fas.harvard.edu http://www.fas.harvard.edu/mailman/listinfo/gov1000-list
