1 There is a significant difference between the profits from the two stores.

2 There is a difference between the profits from the two stores, and it is equal to the standard deviation.

3 There is no difference between the profits from the two stores.

4 The profit earned from both stores is equal to the standard deviation.

5 The profit earned from one store is greater than the profit earned from the other.

Answer 2

Do you know what alternative and null hypothesis mean?

Answer 3

sorta arent that pretty much the opposite of each other?

Answer 4

Yes. That is one way of thinking about it that is reasonable.

The alternative is seeing some cause and the null is not seeing that cause, which are opposites.

So, if "There is a difference between the profits earned from the two stores" is what you are looking for in the study, what is the opposite of that?

Answer 5

The opposite would be there is no difference between the profits of the two stores.

Answer 6

Exactly. So that is the answer.

Answer 7

thanks

Answer 8
