WebHypothesis Test for One Population Proportion (1-Prop Test) State the random variable and the parameter in words. x = number of successes. I = proportion of successes. State the null and alternative hypotheses and the level of significance. Ho: p = po, where po is the known proportion. HA: p < po. WebFor example, in a two-tailed Z test with critical values -1.96 and 1.96 (corresponding to 0.05 significance level) the critical regions are from -∞ to -1.96 and from 1.96 to +∞. Therefore, if the statistic falls below -1.96 or above 1.96, the null …
