Q: In baseball, the designated hitter rule is the common name for Major League Baseball Rule 5.11, adopted by the American League in 1973. The rule allows teams to have one player, known as the designated hitter (abbreviated DH), to bat in place of the pitcher. Since 1973, most collegiate, amateur, and professional leagues have adopted the rule or some variant. MLB's National League and Nippon Professional Baseball's Central League are the most prominent professional leagues that do not use a designated hitter.
Can we conclude that do pitchers have to hit in the national league?

While Zipf's law works well in many cases, it tends to not fit the largest cities in many countries; one type of deviation is known as the King effect. A 2002 study found that Zipf's law was rejected for 53 of 73 countries, far more than would be expected based on random chance. The study also found that variations of the Pareto exponent are better explained by political variables than by economic geography variables like proxies for economies of scale or transportation costs. A 2004 study showed that Zipf's law did not work well for the five largest cities in six countries. In the richer countries, the distribution was flatter than predicted. For instance, in the United States, although its largest city, New York City, has more than twice the population of second-place Los Angeles, the two cities' metropolitan areas (also the two largest in the country) are much closer in population. In metropolitan-area population, New York City is only 1.3 times larger than Los Angeles. In other countries, the largest city would dominate much more than expected. For instance, in the Democratic Republic of the Congo, the capital, Kinshasa, is more than eight times larger than the second-largest city, Lubumbashi. When considering the entire distribution of cities, including the smallest ones, the rank-size rule does not hold. Instead, the distribution is log-normal. This follows from Gibrat's law of proportionate growth.

Problem: Text: The home field curse affects the host team of the Super Bowl. So far no team has yet managed to reach the Super Bowl in their home stadium. Four teams with Super Bowls in their home venue have qualified for the divisional playoffs: the 1994 Miami Dolphins, the 1998 Miami Dolphins, the 2016 Houston Texans, and the 2017 Minnesota Vikings, the Vikings being the first to qualify for their conference's title game. From 1966--2011 (excluding the six Super Bowl games held in a stadium without a professional team), the Super Bowl host team has had 11 winning seasons, four split seasons, and 25 losing seasons. Mathematically, the probability of that many losing seasons or more occurring by chance (assuming a 50 percent chance of having a losing season (disregarding .500 seasons)) is 7.69 percent. It should be noted, however, that the Super Bowl host stadium is selected several years before the game is played, without regard to the teams that qualify.

Question: has a superbowl team ever played at their home stadium?
