vs

We have here given,   
Population mean for given sample=873.3  
Sample mean=875.1          
Sample standard deviation s=5.32      
Sample size =n=   23          
                  
Degree of freedom = n-1 =22      
                  
  
                  
t test statistic formula is

P value is 0.0594................................by using =TDIST(1.623,22,1) Excel command.

P value is 0.0594 > 0.05

Therefore, we fail to reject H0.
