Questions: What would be the expected difference between the means when applied to the null hypothesis? Select one: a. 0 . b. 1 . c. Theoretical. d. Infinite.

Solution Steps

The null hypothesis (\( H_0 \)) typically states that there is no significant difference between the groups being compared. In the context of means, it implies that the difference between the means of the two groups is zero.

Under the null hypothesis, the expected difference between the means of the two groups is zero. This is because the null hypothesis assumes that any observed difference is due to random chance.

Given the options:

• a. 0
• b. 1
• c. Theoretical
• d. Infinite

The correct answer is a. 0, as this aligns with the expected difference under the null hypothesis.
