Wait, mu = 110? That seems kinda random...

Null hypothesis should state equality, so D is valid.

I feel confused because I thought null hypotheses could also be about inequalities, but now I’m not so sure.

I practiced a question similar to this, and I recall that null hypotheses often involve a specific value, which makes me lean towards D as well.

I'm not entirely sure, but I remember something about null hypotheses usually being about equality, so C seems off to me.

I think a null hypothesis should state something like "mu = value," so maybe D is the right choice?

Hmm, the null hypothesis needs to be a testable statement about a population parameter. I think option D, "mu = 110," could work, but I'll review the others just to make sure.

I'm a bit confused on this one. The null hypothesis is supposed to be a specific numerical value, right? I'm not sure any of these options fully fit that criteria.

I've got this! The null hypothesis is a statement of no difference or no effect. Option C clearly fits that description, so that's my pick.

Okay, let me see here. The null hypothesis is usually stated in terms of a parameter, like the mean or proportion. I think option C looks promising, but I'll double-check the others just to be sure.

Hmm, this is a tricky one. I'll need to think carefully about the definition of a null hypothesis to determine which of these options is valid.

This exam question is making me hungry. I wonder if the null hypothesis involves the mean number of cookies in a jar?
