An obstetrician believes that the percentage of mothers who smoke 21 cigarettes or more is less than 3% today. She randomly selects 160 pregnant mothers and finds that 2 of them smoked 21 or more cigarettes during pregnancy. Test the researcher's statement at the g = 0.1 level of significance. What are the null and alternative hypotheses? = 0.03 versus H: p Ho: P (Type integers or decimals. Do not round.) 0.03 Because npo (1- Po) = V10, the normal model V be used to approximate the P-value. (Round to one decimal place as needed.)
