In 2021, a poll showed that 363 out of 600 randomly selected of drivers said they check their mobile device while driving. Use this data to test the claim that more than 55% of drivers said they check their mobile device while driving at α=0.05 significance level. Form null and alternative hypotheses for this test: Run the test to find the test statistic and p-value. Show work. Using either the p-value OR the rejection region method, make a decision about the null hypothesis? Explain. Write a conclusion for this test in context to the problem. Find the 90% confidence interval for the population proportion of drivers that said they check their mobile device while driving. Does the confidence interval confirm the results of your hypothesis test? Explain.
