Question

Consider the following statistics. 
Sample size (n) = 10 
Sample mean (T) = 66 
Sample variance (S²) = 10 
If the population mean is 64, is there a significant difference between the population mean and sample mean? (Use: The tabulated value of t for 9 degrees of freedom at a 5% level of significance is 2.26.) 
No, because 1.90 < 2.26. 
Yes, because 1.90 < 2.26. 
No, because 2 < 2.26. 
Yes, because 2 < 2.26.
