Note: we will not find p-values for the t table: conclusion. 8. 6 large sample significance tests for a proportion: requires a large random sample, ho : p = po, ha : po. Or ha : p > po one tailed upper. Or ha : p < po one tailed lower. Variable is qualitative (binomial) two tailed: = (cid:3043) (cid:3043)(cid:3290)
