Answer:
2.6549
Step-by-step explanation:
Since the sample size n=65, the degrees of freedom is n-1=65-1=64
The critical value=[tex]\frac{t_{0.01}}{2}=t_{0.005}[/tex]
Using the t-table and selecting df=64 and [tex]\alpha=0.01[/tex] since it’s a 2 tail the corresponding t-score is 2.6549
Therefore, the critical value is 2.6549
