Final Answer :
A
Explanation :
The null hypothesis typically states that there is no significant difference between two or more groups or variables. In this case, the null hypothesis should state that the population mean is equal to a specific value (in this case, 60). Option A states the appropriate null hypothesis, while option B refers to a sample mean and option C is the alternative hypothesis. Option D is incorrect because not all choices are appropriate null hypotheses.
