Sampling Theory
... Multistage Sampling Methodologies • Generally used to counter presence of nuisance parameter (unknown) • Used in situations where the optimal sample size required is not known a-priori • Sampling done in two or more stages • First Stage: Select a ‘small’ sample m • Use this pilot sample to get an e ...

... were questioned while they were hypnotized and gave 14, 22, 18, and 17 accurate responses. The four participants in the control group gave 20, 25, 24, and 23 accurate responses. Using the .05 significance level, do hypnotized witnesses perform differently than witnesses who are not hypnotized? ...

... individual players. For the 350 regular starters, Webb has found their mean batting average is 0.229, with a standard deviation of 0.024. His sister is appalled that baseball players get paid the salaries they do and get a hit less than 25% of their attempts at bat. To further her argument, she asks ...

... A more typical way to put it • Null hypothesis (H0): your sample mean is not different from the population mean (the apparent difference is simply due to error inherent in the sampling process) • We decide whether to accept or reject the null hypothesis by performing one-sample t-test • Let’s say α ...
