A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 93% of patients taking the drug are healed within 8 weeks. In clinical trials, 212 of 226 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the a = 0.01 level of significance. Because npo (1- Po) = 10, the sample size is v 5% of the population size, and the sample v the requirements for testing the hypothesis v satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: O versus H,: (Type integers or decimals. Do not round.) Find the test statistic, zo Zo = (Round to two decimal places as needed.) Find the P-value. P-value = (Round three decimal places as needed.) Choose the correct conclusion below. O A. Do not reject the null hypothesis. There is insufficient evidence to conclude that more than 93% of patients taking the drug are healed within 8 weeks. O B. Do not reject the null hypothesis. There is sufficient evidence to conclude more than 93% of patients taking the drug are healed within 8 weeks. OC. Reject the null hypothesis. There is sufficient evidence to conclude that more than 93% of patients taking the drug are healed within 8 weeks. O D. Reject the null hypothesis. There is insufficient evidence conclude that more than 93% of patients taking the drug are healed within 8 weeks.

A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 93% of patients taking the drug are healed within 8 weeks. In clinical trials, 212 of 226
patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the = 0.01 level of significance.
Because npo (1 - Po) =|
V 10, the sample size is
V 5% of the population size, and the sample
V the requirements for testing the hypothesis
V satisfied.
(Round to one decimal place as needed.)
What are the null and alternative hypotheses?
versus H,:
Но
(Type integers or decimals. Do not round.)
Find the test statistic, zo-
Zn = (Round to two decimal places as needed.)
Find the P-value.
P-value =
(Round to three decimal places as needed.)
Choose the correct conclusion below.
O A. Do not reject the null hypothesis. There is insufficient evidence to conclude that more than 93% of patients taking the drug are healed within 8 weeks.
O B. Do not reject the null hypothesis. There is sufficient evidence to conclude more than 93% of patients taking the drug are healed within 8 weeks.
OC. Reject the null hypothesis. There is sufficient evidence to conclude that more than 93% of patients taking the drug are healed within 8 weeks.
O D. Reject the null hypothesis. There is insufficient evidence to conclude that more than 93% of patients taking the drug are healed within 8 weeks.
