Answer 1

We have to test whether diabetes has a protective effect on breast cancer incidence for adult females.

It is a two tailed hypothesis test because diabetes effect on breast cancer incidence can be positive or negative depending on the data.

Therefore, we can write our hypotheses as following

Null hypothesis:- diabetes has no significant protective effect on breast cancer incidence for adult females

Alternate hypothesis:- diabetes has a significant protective effect on breast cancer incidence for adult females
