Eli is looking for a one-bedroom apartment and is investigating whether the mean cost is less now than what it was last year. A random sample of apartments had a sample mean ž of $1,180 per month. Assuming all conditions for inference are met, El will conduct a hypothesis test as part of his investigation. Which of the following is the correct set of hypotheses? Họ : 4= 1,200 H:4> 1,200 Họ : - 1,200 H : A< 1,200 H, :2 1,200 H:< 1,200 H : - 1,180 H :2 1,180 Ho :- 1,180 H :< 1,180
