Answer:
Null hypothesis: 
        
Alternative hypothesis: 
  
 
    
If we compare the p value and the significance level given  we see that
 we see that  so we can conclude that we FAIL to reject the null hypothesis, and the the actual mean is not significantly lower than 530 at 5% of significance.
 so we can conclude that we FAIL to reject the null hypothesis, and the the actual mean is not significantly lower than 530 at 5% of significance.      
Step-by-step explanation:
1) Data given and notation        
 represent the mean for the sample
 represent the mean for the sample    
 represent the standard deviation for the sample
 represent the standard deviation for the sample   
 sample size
 sample size        
 represent the value that we want to test
 represent the value that we want to test   
 represent the significance level for the hypothesis test.
 represent the significance level for the hypothesis test.      
t would represent the statistic (variable of interest)        
 represent the p value for the test (variable of interest)
 represent the p value for the test (variable of interest)    
2) State the null and alternative hypotheses.        
We need to conduct a hypothesis in order to determine if the claim thet the handle on average is 530 bags per hour:      
Null hypothesis: 
        
Alternative hypothesis: 
        
We don't know the population deviation and the sample size is lees than 30, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:        
 (1)
 (1)        
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".    
3) Calculate the statistic        
We can replace in formula (1) the info given like this:        
 
        
4) Calculate the critical value
We need to begin calculating the degrees of freedom

The critical value for this case would be :

The value of a that satisfy this on the normal standard distribution is a=-1.75 and would be the critical value on this case zc=-1.75
5) Calculate the P-value        
Since is a one-side upper test the p value would be:        
 
    
6) Conclusion        
If we compare the p value and the significance level given  we see that
 we see that  so we can conclude that we FAIL to reject the null hypothesis, and the the actual mean is not significantly lower than 530 at 5% of significance.
 so we can conclude that we FAIL to reject the null hypothesis, and the the actual mean is not significantly lower than 530 at 5% of significance.
