Answer:
The 90% confidence interval  
The null hypothesis is  
The alternative hypothesis 
The distribution test statistics is 
The rejection region is  p-value <  
 
The decision rule is reject the null hypothesis 
The conclusion is 
       There is sufficient evidence to conclude that there are more passengers riding the 8:30  train 
The p-value  is  
Step-by-step explanation:
From the question we are told that
     The first sample size 
     The first sample mean is  
     The first standard deviation is 
     The second sample size is 
     The second sample mean is  
     The second standard deviation is 
given that the confidence level is 90% then the level of significance is mathematically represented as 
           
          
Generally the critical value of  obtained from the normal distribution table is
 obtained from the normal distribution table is  
    
Generally the pooled variance is mathematically represented as 
         
       
      
Generally the standard error is mathematically represented as
      
=>  
=>   
Generally the margin of error is mathematically evaluated as  
       
        
        
Generally the 90% confidence interval is mathematically represented as
      
      
      
The null hypothesis is  
The alternative hypothesis 
Generally the test statistics is mathematically represented as 
      
=>   
=>   
Generally the degree of freedom is mathematically represented as 
      
       
      
The p-value is obtained from the student t distribution table at degree of freedom of 73 at 0.05 level of significance 
     The value is  
Here the level of significance is  
Given that the p-value <  then we  reject the null hypothesis
 then we  reject the null hypothesis 
Then the conclusion is  
   There is sufficient evidence to conclude that there are more passengers riding the 8:30  train
