Final Answer :
D
Explanation :
The null hypothesis for a t-test for dependent means typically states that there is no difference between the means of the two related groups, which is represented by the equation μ1 = μ2. This is best reflected in choice D, despite the encoding issues, as it suggests equality between two means.
