Question

Suppose we want to know whether students who attend a top business school have higher earnings. what is the null hypothesis?

Answer 1

The null hypothesis is One-sided.

We should do a one-sided test because our main concern is whether the average wages of graduates from the top 50 business schools are higher than those of their non-graduate counterparts.

We would do a two-sided test if we were curious to know whether the wages of graduates from the top 50 business schools were different (either greater or lower) than those from the other institutions.
