A professional employee in a large corporation receives an average of 41.0 emails 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 40 employees showed they were receiving an an average of 33.3 e-mails per day. The computer server through which the e-mails are routed showed that o=15.2 . 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. What are the null and alternate hypotheses? HO : u + 41.0 e-mails; H1 : µ = 41.0 e-mails H0: μ-41.0 e-mails; H1 : μ +41.0 e-mails HO : µ = 41.0 e-mails; H1: µ < 41.0 e-mails H0: μ-41.0 e-mails; H1 : μ >41.0 e-mails HO : µ + 41.0 e-mails; H1: µ > 41.0 e-mails

![A professional employee in a large corporation receives
an average of 41.0 emails 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 40 employees showed
they were receiving an an average of 33.3 e-mails per day.
The computer server through which the e-mails are
routed showed that o=15.2 . 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. What are the null and alternate
hypotheses?
