In a program designed to help patients stop smoking, 198 patients were given sustained care, and 82.0% of them were no longer smoking after one month. Use a 0.05significance level to test the claim that 78% of patients stop smoking when given sustained care. Use the P-value method. Use the normal distribution as anapproximation to the binomial distribution.The Hypotheses test: Choose one of these( answer A or B or C)А. Но: р - 0.78В. Но: р - О.78С.

Weight loss: In a study to determine whether counseling could help people lose weight, a sample of people experienced a group-based behavioral intervention, which involved weekly meetings with a trained interventionist for a period of six months. The following data are the numbers of pounds lost for 14 people. Assume the population is approximately normal. Perform a hypothesis test to determine whether the mean weight loss is greater than 13 pounds.

The coach of a very popular men’s basketball team claims that the average distance the fans travel to the campus to watch a game is 35 miles. The team members feel otherwise. A sample of 16 fans who travel to games was randomly selected and yielded a mean of M= 36 miles and s= 5 miles. Test the coach’s claim at the 5% (.05) level of significance. one-tailed or two-tailed test: State the hypotheses: df= tα or t value for the critical region = sM = t (test statistic)= Decision:
