Question 10 1 pt 91 Details Past studies have indicated that the percentage of smokers was estimated to be about 32%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 2141 people and found that 647 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduced. a) Identify the null and alternative hypotheses? H: 2 V H: 2 V b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed Oright-tailed two-tailed c) Identify the appropriate significance level. d) Calculate your test statistic (Use Ộ rounded to 4 decimal places). Write the result below, and round your test statistic to 4 decimal places. e) Calculate your p-value. Write the result below, rounded to four decimal places. f) Do you reject the null hypothesis? O We reject the null hypothesis, since the p-value is less than the significance level. o We reject the null hypothesis, since the p-value is not less than the significance level. We fail to reject the null hypothesis, since the p-value is less than the significance level. We fail to reject the null hypothesis, since the p-value is not less than the significance level. g) Select the statement below that best represents the conclusion that can be made. There is sufficient evidence to warrant rejection of the claim that the percentage of smokers is less than 3298 O There is not sufficient evidence to warrant rejection of the claim that the percentage of smokers is less than 32%. The sample data support the claim that the percentage of smokers is less than 32%. There is not sufficient sample evidence to support the claim that the percentage of smokers is less than 3290
