Are These Questions Wrong?

Team, I am concerned about these two questions and the confusion over null and alternative hypotheses.

The null is the default/assumed relationship. The alternative is the research/contrary hypothesis: what is to be tested.

See the two questions below. How can the alternative coefficient be greater than or equal to zero?

The answers are A and B. I have brought this to the attention of the curriculum provider.

Back in stats class, we were taught to put the equality portion in the null hypothesis.

Yes, that is what I remember too. The questions (and answers) are counterintuitive to me. Thanks for weighing.
