O no, z-score (samples)(2) if pop sd known. O no, t-score (samples (4) if pop sd unknown. If asking for when a success will occur > exponential (6) How many successes will occur over a period > Is np >= 10, nq >= 10: no, binominal (11, yes. Poisson discrete (7) must be given constant rate of success. = ; = ; cv = 1. P (s z t)=p( z t ) p(z s) The sd of sample mean (2): x= . P (x> y)=p ( x y >0); e= 5. If <= or >, add 0. 5. if, >= or 10 and n(1-p) >10. Sample mean: n ( x1+ x n)= in conditions. Sd ( a ) sd(b) n/n = sample size/population size.
