10.2.18 Question Help 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 92% of patients taking the drug are healed within 8 weeks. In clinical trials, 221 of 236 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the 0.05 level of significance Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). Because npo (1-P) = 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)

Answer 1

n = 236, p = 0.92

np(1-p) = 236*0.92*0.08 = 17.4

Because np(1-p) = 17.4 > 10, the sample size is less than 5% of the population size, and the sample <no options> the requirements for testing the hypothesis is satisfied.

Please note that due to non-availability of options, one option could not be figured out. Please fill it according to the other answers.
