Question

Artan 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, 214 of 231 patients suffering from acid reflux disease were heated after Test the manufacturer's claim at the a=0.1 level of significance. Because npo (-)-010, the sample size is 5% of the population size, and the sample requirements for testing the hypothesis satisfied (Round to one decimal place as needed.)

Answer 1

= 142.4 > 10

is , the sample size is 5% less than population

Random

is satisfied

because np(1-p) = 142.4 > 10, the sample size is less than 5% of population size, and sample can be reasonably assumed to be random , the rquirement for testing the hypothesis is satisfied

Please let me know in case of any doubt.

Thanks in advance!
