Q: State an example of null (H0) hypothesis

The term "null (H0) hypothesis" in statistical tests is used to investigate whether the "null (H0) hypothesis" is true or false. For example, We measure the blood pressure in women and men. Our "null (H0) hypothesis" would be: the blood pressure of women is not significantly different from the blood pressure of men. The "alternative (H1) hypothesis" would be: the blood pressure of women is significantly different from the blood pressure of men. Then we conduct the appropriate statistical test to investigate which of the two hypotheses is TRUE. In another example, We want to investigate the wages between two countries. The "null (H0) hypothesis" would be: the wages are not significantly different between the two countries The "alternative (H1) hypothesis" would be: the wages are significantly different between the two countries

Hope this helps. All the best!
