what is test statistic and conclusion

4. A professional employee in a large corporation receives an average of u= 40.3 e- mails per day. Most of these e-mails are from other employees in the company. Because of the large number of e-mails, employees find themselves distracted and are unable to concentrate when they return to their tasks. In an effort to reduce distraction caused by such interruptions, one company established a priority list that all employees were to use before sending an e-mail. One month after the new priority list was put into place, a random sample of 32 employees showed that they were receiving an average of x= 33.3 e-mails per day. The computer server through which the e-mails are routed showed that o = 15.4. Has the new policy had any effect? Assume the distribution is approximately normal. Use a 5% level of significance to test the claim that there has been a change (either way) in the average number of e-mails received per day per employee. a.
