PPT-6.2 Tests of Significance

Formalizing We saw in the last section how to find a confidence interval In this section we use the confidence interval to come up with a formal test to be able to say whether or not we think a sample is representative of the population We assume n is at least 30 and hence may use s to estimate . 205 Types WR WRM HVAC POWER FREQUENCY RESONANT TEST SYSTEMS brPage 2br Fig 1 HVAC resonant test system type WRM PPLICATION FACTS IN BRIEF Resonant test systems are applied to the generation of high voltage AC of power frequency for routine type and Stella Jackson (saj504@york.ac.uk).
