Baseball player George Springer won the 2017 World Series Most Valuable Player award after his outstanding hitting performance in the playoffs. In the regular season, he got a hit in 28.3% of his at-bats. In the playoffs, he had 11 hits in 29 at-bats. Does this performance provide convincing evidence that George Springer'sability to hit increased in the playoffs?

Explain what it means if the null hypothesis is true.

A) If George Springer took millions of at-bats in the same conditions as the playoffs, he would get a hit in 28.3% of his at-bats.

B) If George Springer took millions of at-bats in the same conditions as the playoffs, he would get a hit in 37.9% of his at-bats.

A or B?
