(a) Identify the claim and state the null and alternative hypothesis. (b) Determine whether the test is left-tailed, right-tailed, or two-tailed, and determine whether to use a z-test, t-test, chi-squared test, or F-test. (c) Find the Test Statistic and P-Value and draw and label the distribution. (d) State your conclusion about the null hypothesis. (e) Write the final conclusion that addresses the original claim. Round all test statistics to 2 decimals, and P-values to 4 decimals. 1) From a random sample of 49 Super Bowls, 28 of them were won by teams in the National Football Conference (NFC). Use a 0.05 significance level to test the claim that the proportion of NFC teams winning the Super Bowl is greater than 50%.
