Evaluate if the company should allocate more resources to improve its average TiQ. 

Access the Call Center Waiting Time file. Each row in the database corresponds to a different call. The column variables are as follows: 

  • ProtocolType: indicates protocol type, either PT or PE
  • QueueTime: Time in Queue, in seconds
  • ServiceTime: Service Time, in seconds
  • Perform a test of hypothesis to determine whether the average TiQ is lower than the industry standard of 2.5 minutes (150 seconds). Use a significance level of α=0.05.  
  • Evaluate if the company should allocate more resources to improve its average TiQ. 
  • Perform a test of hypothesis to determine whether the average ST with service protocol PE is lower than with the PT protocol. Use a significance level of α=0.05.  
  • Assess if the new protocol served its purpose. (Hint: this should be a test of means for 2 independent groups.) 
  • Submit your calculations and a 175-word summary of your conclusions
