A 2018 poll of 2246 randomly selected U.S. adults found that 44.08% planned to watch at least a"fair amount" of a particular sporting event in 2018. In2014, 51% of U.S. adults reported planning to watch at least a"fair amount." Use a significance level of 0.05

a) State the null and alternative hypotheses. Let p be the proportion of U.S. adults that planned to watch at least a"fair amount" of the sporting event.

b) compute z-test statistic

c) compute p-value

d) Use the sample data to construct a 90% confidence interval for the population proportion. How does your confidence interval support your hypothesis testconclusion?
