E-mails Priority List:A professional employee in a large corporation receives an average of41.7emails per day.Most of these emails are from other employees in the company.Because of the large number of emails, employees find themselves distracted and are unable to concentrate when they return to their tasks (Reference:The Wall Street Journal).In an effort to reduce distraction caused by such interruptions, one company established a priority list that all employees were to use before sending email.One month after the new priority list was put into place, a random sample of 45 employees showed that they were receiving an average of36.2 emailsper day.The computer server through which the emails are routed showed that=18.5

=18.5emails per day.Use a 5% level of significance to test the claim that the average number of emails received per day per employee is now less.Has the new policy had any effect?

Perform a hypothesis test using the 5-step process:

a)State Ho and H1 in symbols and in words.Identify which hypothesis is the claim and the type of test (right-tail, left-tail, two tail).

b)Determine the critical value and label it(for example, z = 1.96or t = -2.421, etc).

c)Compute the test value, z or t.If you are using the p-value method, then compute the test value and include the p-value of the test (4 decimal places).

d)Make the decision toReject HoorDo not reject Ho.

e)State your complete conclusion in the context of the claim.
