Document Summary
1 in 100 would be the outliers (really short or really tall) Calculus z"s converted to p"s -2 2 integrate that function from -2 to +2 and you end up with . 95 that"s the area b/w those two points. ^^^^^^ use that website that"s on the slide it will help you . 1 walters lecture: statistical inference soan 2120 i n t r o d u c t o r y r e s e a r c h m e t h o d s calculating p-values ! How do we know that a z-score of plus or minus 2 translates to a p-value of . 05 ! Using sample information to estimate population values ! This is the sampling distribution over repeated samples. randomly take 10 people from that population then calculate the mean of their height take second random sample take third random sample, etc.
