Question
Previously, 6% 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 6% today. She randomly selects 130 pregnant mothers and finds that 5 of them smoked 21 or more cigarettes during pregnancy. Test the researcher's statement at the a 0.05 level of significance. What are the null and alternative hypotheses? versus H, Họ: (Type integers or decimals. Do not round.) Because npo (1- Po) = 10, the normal model (Round to one decimal place as needed.) V be used to approximate the P-value. Find the P-value. P-value = (Round to three decimal places as needed.) Is there sufficient evidence to support the obstetrician's statement? O A. No, do not reject the null hypothesis because the P-value is greater than a.
