Question

A professional employee in a large corporation receives an average of μ = 39.9 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 distractions 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 = 33.6 e-mails per day. The computer
server through which the e-mails are routed showed that σ = 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.
