... A more important example, having the same mathematical properties as the thumbtack example, arises in genetics through the phenomenon of recombination (crossing-over). There is some probability that a recombination event occurs between two gene loci when genetic material is passed on from parent to ...

One-sample categorical data (approximate)
... The standard error The major conceptual difference from the hypothesis test is that we don’t know p, and we need p in order to calculate the standard error. The simplest and most natural thing to do (and what we will do in this class) is to use the observed value, p̂, in calculating the standard err ...

... You actually already know how to find the critical value for hypothesis tests of population Mean using large samples. Remember the Excel function NORMSINV(probability)? It allows us to determine the x value (same as zscore) for a standard normal distribution where we know the area (probability) as m ...

To compare the responses to the two treatments in a matched pairs design, apply the one-sample t procedures to the observed differences (one treatment observation minus the other). The parameter m is the mea ...

... Once a sample is drawn, the following steps are performed: • formulate the hypotheses: the null or status quo, and the alternate (which are complementary) • select a confidence level and estimate the corresponding significance level (say, 0.01 or 0.05) • identify a test statistic (or random varia ...
