Question 1 Not yet answered Marked out of 1.00 P Flag question A professional employee in a large corporation receives an average of 399 e-mails per day. Most of these emails 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 45 employees showed that they were receiving an average of x = 33.6 e-mails per day. The computer server through which the e-mail are routed showed that 17.3. Has the new policy had any effect? 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. Find (or estimate) the P-value Select one: O a. 0.004 ob. 0985 O C. 0.993 O d. 0.015 O e. 0.996
