In a program designed to help patients stop smoking, 188 patients were given sustained care, and 83.0% of them were no longer smoking after one month. Use a 0.05 significance level to test the claim that 80% of patients stop smoking when given sustained care. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. Part 1 Let p denote the population proportion of patients who would no longer be smoking after one month when given sustained care. Identify the null and alternative hypotheses. H0: p=. 80 H1: p. 80 (Type integers or decimals. Do not round.) Part 2 Identify the test statistic. Z=
