Previously, 4% of mothers smoked more than 21 cigarettes during their pregnancy. An obstetrician believes that the percentage of mothers who smoke 21 cigarettes or more is less than 4% today. She randomly selects 140 pregnant mothers and finds that 2 of them smoked 21 or more cigarettes during pregnancy. Test the researcher's statement at the a = 0.1 level of significance. What are the null and alternative hypotheses? Ho: P = 0.04 versus H1: p < 0.04 (Type integers or decimals. Do not round.) Because npo (1- Po) = V 10, the normal model V be used to approximate the P-value. (Round to one decimal place as needed.)
