In a recent year, a poll asked 2333 random adult citizens of a large country how they rated economic conditions. In the poll, 20% rated the economy as Excellent/Good. A recent media outlet claimed that the percentage of citizens who felt the economy was in Excellent/Good shape was 19%. Does the poll support this claim? a) Test the appropriate hypothesis. Find a 90% confidence interval for the proportion of adults who rated the economy as Excellent/Good. Check conditions. b) Does your confidence interval provide evidence to support the claim? c) What is the significance level of the test in b? Explain. a) Let p be the proportion of adult citizens who felt the economy was in Excellent/Good shape. What are the null and alternative hypotheses for the test? O A. Ho: P= 0.19 vs. HA: P> 0.19 O B. Ho: P = 0.20 vs. HA: P # 0.20 O C. Ho: P = 0.19 vs. HA: P # 0.19 O D. Hoi p = 0.20 vs. HA: P
