Activity 3: Hypothesis Test for a Proportion Using the same data from Activity 2, we will now conduct hypothesis testing and see if our conclusions are the same as in Activity 2 using confidence intervals. We can use a z-test for a sample if it is a random sample from a population and if n (sample size) times p0 (calculated proportion) as well as n times (1 - p0 ) are both at least 10.
REFLEXIONES SOBRE LA SA LUD Un anterior número de esta revista se ocupó de la educación, el tema de este número es la salud. Aplicar políticas sociales que mejoren la salud es a la vez más sencil o y más complicado que hacerlo en educación.
