In a program designed to help patients stop smoking, 189 patients were given sustained care, and 83.1% of them were no longer smoking after one month. Use a 0.10 significance level to test the claim that 81% of the patients stopped smoking when giving sustained care. Use the P value method. Use the normal distribution as an approximation to the binomial distribution. Let Pete denote the population proportion of patients who will no longer be smoking after one month when given sustained care period identify the null and alternative hypothesis.
