Final Answer :
D
Explanation :
The "<" symbol is used in alternative hypotheses to indicate a one-tailed test, which means we are only interested in finding out if the sample mean is significantly less than or greater than the population mean (not both). This makes sense in certain situations where we have a clear directional prediction. The null hypothesis does not include any symbols, as it simply states that there is no significant difference or relationship between variables. Therefore, option D is the best choice.
