A 2018 poll of 2214 randomly selected U.S. adults found that 45.62% planned to watch at least a "fair amount" of a particular sporting event in 2018. In 2014, 51% of U.S. adults reported planning to watch at least a "fair amount." a. Does this sample give evidence that the proportion of U.S. adults who planned to watch the 2018 sporting event was less than the proportion who planned to do so in 2014? Use a 0.05 significance level. b. After conducting the hypothesis test, a further question one might ask is what proportion of all U.S. adults planned to watch at least a "fair amount" of the sporting event in 2018. Use the sample data to construct a 90% confidence interval for the population proportion. How does your confidence interval support your hypothesis test conclusion? a. State the null and alternative hypotheses. Let p be the proportion of U.S. adults that planned to watch least a "fair amount" of the sporting event. Ho: P I (Туре cimals. Do not round.)
