Which inequality represents the situation? The maximum weight, w, an elevator can lift is 2,200 pounds. w ≥ 2,200 w > 2,200 w

IgorLugansk [536]

Answer:

w ≤ 2200

Step-by-step explanation:

If a lift can lift a maximum weight of 2200pounds, this means that the lift can not life a weight greater than 2200pounds. For the expression needed, the inequality sign to use will be a less than or equal to sign( ≤ ).

Answer:

$H_0:\mu =45\\\\H_a:\mu\geq 45$

Step-by-step explanation:

Since we have given that

A toy manufacturer claims that the mean time that its top-selling toy captures children's attention is at least 45 minutes.

Since we need to carry out a hypothesis test whether he can refute the claim.

We always take the alternate hypothesis such that it should satisfy the given statement.

And the null hypothesis can be equal to mean or other than that is given in alternate hypothesis.

So, hypothesis :

$H_0:\mu =45\\\\H_a:\mu\geq 45$
