... whether a women's studies department should be opened. The university has 30,000 students of which 25,000 are men and 5,000 are women. A common method of sampling can be done as follows: 1. Divide the sampling frame into groups of units, called strata. The strata are chosen because we have a special ...

... Use the Stat pull-down menu. Choose Tables and then Chi Squared Test. Your output will show O and E as a single table. You will be given a p-value for the hypothesis of Independence or Homogeneity. For a test of Normality, when sample mean and variance are to be computed from the sample, put your co ...

... the correction for continuity. After having tried several problems, my impression (possibly wrong) is that, when p0 is close to .5, the correction improves accuracy, but as p0 gets further and further away from .5 it may actually do more harm than good. The moral is that, if it is a very close call, ...

To estimate Analytic:( x ) I used repeat measurements of 10 PCB 153 calibration standards and of 7 p,p’-DDE calibration standards. For both chem ...
